Need to learn from your experience.

Not looking forward to this wrestling event but excited to get it done.

Is it a 1-person job for my elder self?

Is it easier to put the brackets on the frame separately or have them attached to the front bumper?

Bumper supported? How?

Car on jack stands or on the tires?

Any hints on alignment?

Thanks

Mike

I am in the middle of painting my 70 Lemans. I have taken it on and off several times. You can take it off by yourself. It is somewhat tricky. I would not recommend putting it on by yourself. The header panels are very fragile at the lip that sits behind the bumper.
First take off the valance panel and remove the license plate bracket. I have learned to leave the large brackets attached to the frame if you want to keep the original alignment. Remove bolts that attach inner structure to the larger brackets. There are two large bolts that are visible through the two holes in the top of the radiator support. Remove those last after you have something in place to rest the bumper on. It would be great to have something that fits just below the height of the bumper bracket. I use a garden wagon and several moving blankets from HF. Once you are ready for final placement remove the two top bolts and tip the front of the bumper up towards the windshield.to clear the two upper brackets from under the header panel. I hope this helps.

Even though your bumper is not aligned presently, it may be easier for you to get the bolts for the large brackets installed in the frame before attaching them to the bumper. Do not tighten them up until you have it where you want it. In my first reply I believed that you were removing and replacing. Just reverse the process I described.

Thanks for the quick help, 62olds!

My bumper has been off for well over 10 years if not more so I don't remember removing it.

I did put a lot of time into repairing the header and definitely don't want to ding it but it's only primed so scratches won't be a disaster. Cracking an edge off it would be disaster, at least for me.

Sounds like I should put the big brackets on the frame first and leave them loose enough to get the bumper bolts in. I think this is what the repair manual said but it conveniently didn't offer any help wrestling the bumper into place! It's not super heavy, but heavy enough and awkward enough that I'm asking how others managed it.

Your warning about installing myself is noted and I'll get some help. I have a wagon and blankets so understand that part of it.

Are you installing with the front end of the car elevated or sitting on tires on the ground. I assume you're crawling under the bumper to reach the bolts that attach the support to the frame. If so, this sounds very awkward and dangerous.... I don't have a hoist that would make this safer...

Your comment about leaving the stabilizer bolts is a little unclear.

The brackets have rubber insulators that slide into sheet metal pockets on the upper rail of the radiator support. It makes me nervous to think the entire bumper could be supported by those brackets but maybe you are saying the weight will still be on the big lower brackets even though the bolts are removed?

Maybe you are suggesting the bolts between the stabilizer and the big brackets can come out but the brackets will still support the weight? If so, this will give me a little more confidence.

And if I'm interpreting correctly, does this mean that to install, you lift the bumper onto the big brackets, then tilt the top into the header and run the stabilizer bolts in to help keep it from falling?

Thinking this through... if the bumper can be supported by the lower big brackets until the bolts are in place, then I think I need to have the lower brackets a little snug to hold the bumper high enough to avoid whacking the header lip. Does this make sense?

Those two upper bolts in the rubber will hold up the entire bumper. You will be surprised. But you can’t hold it by yourself while you tighten them . Please ask more questions,if I am not being clear about the process.

62olds, this is really helpful and appreciated

I have this done.. the two stabilizer brackets are hanging off the radiator support with the insulators installed. The slots in these stabilizer brackets are easy to access through the holes in the radiator support. Because they are hanging off the rubber grommets, they could get knocked sideways easily or even fall out but they are sitting where they belong.

I'm lost on this step.. please expand. Are you saying to lift the bumper, but hold the bottom of it away from the big lower brackets? And then align the stabilizer brackets with the stabilizer mounts that are on the bumper support? And then put the bolts through the stabilizer bracket into the mounts? And all the while holding the bumper up and away from the bottom brackets?

So at this point the entire bumper could be released and let hang just on those two stabilizer brackets?

So at what point do you push the bumper onto the lower brackets? It sounds like you are saying to attach the stabilizer brackets up top first, then swing the bumper onto the big brackets, then put the bolts into the big brackets. Please tell me if I'm close or way off...

This makes sense as to adjusting. I didn't see gaps in the repair manual so I better go look again. You are saying the assembly manual, which I think is the collection of engineering drawings. I'll look for alignment dimensions there too.

Yes, I will be surprised! But OK...

And understand I need to hold it while someone installs the bolts.

And I'm asking plenty! Like you say, I don't want to damage the header, bumper, or human.

And thanks for commenting on leaving the car on tires on the floor. This makes sense to me for alignment, just wasn't sure about assembly as inserting the bolts through the bumper support into the big brackets sounds pretty awkward.. will have to be on my back, right? With the bumper hanging mostly off the stabilizer brackets?

I like to have the weight of the car sitting on the tires when I line things up.

it has been during this 25 year project. LOL I'll be on more since the car is coming home today!!!
Lot's of good questions being answered here that I would have probably asked.

I'll do a full writeup on this project once it gets done. Hopefully in the next month. Summer is slipping away and I am long over due for drop top cruising.

Just a quick word of advice for alignment of your body panels. Start the back of your doors to the quarter panels. This gap should be about a quarter of an inch. Make sure you have all the weight inside of the doors with the weatherstripping. Get your door glass aligned as best as you can. Then gap your fenders to your doors. Between an 1/8 to 1/4 inch gap is fine. Square up the fenders using an x measurement from the top fender bolt to the opposite fender bolt into the radiator support. Either of the two is ok as long as you use the same bolt on both sides. Everything is still a little loose so you can ad shims as needed. Install the hood, making sure the back of your hood clears the windshield wipers. You may need to move the fenders forward so the back of your hood lines up with the molding on your fenders. Then gap your hood to the fenders. Add your header panel, tighten it up when you are satisfied. Then the bumper and the valance panel. Easy Peasy!

62olds - Your front clip looks perfect. You are doing a really nice job on the body and paint. That must be rewarding.

Thanks for the notes on alignment. That will be useful if I ever get to paint my car. I've had the car almost 20 yrs and have moved it twice - barely running and in pieces. We decided to move again so my goal is to move it in one piece and capable of driving on and off the hauler. Fingers crossed.

Always keep it running unless you are doing a motor or motor swap. Thank you for compliments. I only have a one car garage which has no room to work in. I have to clean up and put the car back every day when I get to work on it. I have to always keep it running. Stay motivated, one task at a time. Good luck.

Reading over your posts, I'm hoping you can help me with my 70 Lemans front valance. I can't figure out what brackets are needed to attach this to the vehicle. I see the brackets for a GTO but they don't seem to have the right hole pattern. Do you know what brackets I need or have a diagram for a lemans valance?

[Shiny]

Welcome to the forum. Hope you get some good help here.

See if these repair and assembly diagrams help.

No brackets. It bolts to the bottom of the bumper, then the signal lights are installed. There’s a filler piece that goes between your radiator support and the valance. I don’t think I have ever seen one. I made one out of masticated rubber. If someone has a photo of it, I’d love to see it. Hopefully this combined with the illustration will help.

[Shiny]

I have not put my valance on, having just moved.

I do know I have two straps that I interpret as the bracket in the attached close-ups.

I am not familiar with a filler... will have to look!

You are probably correct about the two small brackets in the diagram. The last time I removed the valance was in the Spring. I do not remember them. The brackets are probably in the box with the parking lights and associated hardware. Thanks for pointing it out. Something I have to look for. The filler is Number 32 in the first diagram.

Thanks for the filler ID. The drawing says "with AC & HD cooling". Does this mean all AC cars had this part? What is HD cooling?

Is this filler piece metal or plastic or ??
