So I just got my set of del lum bushings I ordered them from summit racing...I researched the info on global west site ...73 is a fiasco
The kit is 1014 all bushings are the same size
The new bushings have two shoulders ....and I cannot get the first step of the shoulder to pass through...either side of the control arm
I would have thought the first shoulder would allow the bushing to pass through and the sec shoulder is the interference fit???
Has anyone installed these bushings before in factory arms....????
Here’s a pic of my arms and pretty sure they are 73 arms..by the stamping and the bushings being the same size frt and rear...
Thanks....Chris

Here is a Youtube video. Looks pretty straight forward. Maybe you got the wrong ones? https://www.youtube.com/watch?v=dUQbcyVINL8

Hi those are lowers I’m working with the uppers which are either same size or different frt to year depending on year
73 is the same size
74 different size frt it rear...
I’m gonna take the arms back to work with the bushings and “re -measure” but looking for some input on install if I’m thinking correctly...

Contact Global West direct, they'll guide you through. Playing around on these forums will only waste time, deal with the people that make it. The people at Global West are awesome folks and will go to all ends of the earth to help you out. The owner himself helped me with a clearence issue. He kept cutting bushings to different thicknesses and next day shipped them to me until my issue was cured, all on his dime.

That's interesting cause I had issues with the rear shackles kit...called talked to Doug he wanted me to drill a hole in the bushing and the area around the frame the bushing went into and pin it....I sent him a video of how loose the bushing was.
I didn't feel comfortable doing that pin and he said he would cut a new bushing for me if I got him a measurement ..I sent measuement and never heard from him again..we were actually emailing back and forth at the time....just figured he didn't want to deal with it.....so I had the bushing knurled and installed it...

When I was looking at purchasing these bushing uppers and lowers I contacted them numerous times not one reply back in questioning the correct kit for the uppers
So ends of the earth maybe for you ......Me not so impressed
I've emailed again also went on there Facebook page and messaged so will see...but perhaps u r right maybe I should call....I order from summit cause they are closer for me with shipping to our friends in Michigan...

Phone calls are personal.

Phone calls are also hard to forget, set aside or ignore.

Did Alexander Graham Bell write a letter to Watson when he needed him? No. He picked up the phone and said, "Mr Watson, come here. I want to see you."

Hey not disagreeing with I you but email is more convienent for me so if they don't offer then I would not be emailing to contact,,,,
If I don't hear back in the week I'll call....
But I was looking for any one else with issue or concerns....

It more than likely will not help. Per Global West, no 2 control arms are exact due to the stamping process. What problem exists on one car of the same make and model, will be different on another. So, pre the owner, they find a happy medium that "should" work on most cars. In my case, there was approximately a 3/16" difference from that happy medium and Global West was right there for me. You won't get that kind of quality or service out of a place like CPP (Chinese Produced Products).

Global West has great products and awesome customer service. I wouldn't hesitate using them again.

Doug is great to talk to. He has made me slight custom subframe bushings and always great to talk to for help. He has had a lot of different vehicles personally . The new videos are great.

Here is a pic of a kit I have for my April '73 Formula These measured for front and rear correctly on the uppers.
I have put this kit in another 73 and front and rear were the same size. Just checked a '75 and front and rear are the same.
The ONLY issue in '73 is the early vs late LOWER control arm bolts, which are 9/16 on later '73's, vs the 1/2 you find from early 73 back to 1970.

Thank you Bruce
I’m using the same vernier it looks like and it’s the Same kit 1014...mine are measuring 1.39” diameter.
My Factory bushings diameter 1.31 “ my control arm holes measure 1.30”diameter
Can u measure the insert outside diameter ...as well too??
Mine measures .994” diameter.

I’m assuming GBW machines the outside diameter to the needed size and the inside diameter remains the same using the same diameter insert....
If that is the case I’ll get my bushings cut down for the .01 interference fit

Could u do me another favour and measure down the hole to the outside to have a thickness of the wall less the insert? Mine measures 1.90 wall thickness.

Mine measures .994”

I know this is elementary but did you clean the jaws first. I have found major discrepancies between pulling a set of calipers out of the drawer and using them vs. pulling a set out and cleaning the jaws prior to using them.

[cnc]

Yes sir they are clean they don’t lay in a drawer exposed and don’t touch each other when put away in its case...so clean no doubt.Being digital I always reset to to zero every time as well...
I’ve measured these bushing numerous times for comparison sakes ...as well as the factory bushings.
The first shoulder of theGBW insert measures 1.37” then steps up to 1.39”.
When I get to work I will measure the factory bushings and these GBW with another fellas Vernier for comparison sakes too just to see how accurate it is.......never know....

[cnc]

So I've measured these bushings all of them factory and GBW with 3 different measuring tools all the same measurements I had using my measuring device...

[Formulabruce]

OK, here is what I have re measured 3 Dims.

Thanks Bruce very much appreciate your help with measuring and passing along the info!!
I'm also a member on another site as well Naztyz28
Here is what I read about these bushings too from another member for that site...
I have the Del-a-lum bushings on both upper and lower control arms and the handling quality is greatly improved. A couple of things to be aware of. The machine shop had to turn the outer shells a few thousandths to get them to press into the control arms. I talked to GW and they said this was normal.

Sooooo looks like it's not an uncommon thing to do then....looks like the road I'll be going down....

Ya know, I think we had to freeze one before install now that I think about it.

Yes I can see that to shrink the bushing for easier install ....
At least your first stage of the bushing ( 1.296" if your control arm size was 1.30"ish like mine) should fit through the control arm hole mine aren't even close.....
I'm thinking that a .002" interference fit should do the trick....tight enough so they won't spin/move down the road...or I might even use a metal adhesive we have at work....we use it when we press on tone wheels onto axle shafts that are not that tight a fit...never seen one come loose it's good stuff....

This is a very good idea and something I would try first before cutting into a not so cheap part.

This all goes back to what the owner said about differences in control arms due to the stamping process.

[cnc]

Yeah guess I could throw one in the freezer and measure after a day or two....be surprised if it would shrink that much...
Also read guy cracked one due to freezing it and pressing it in
I agree on the stamping size differences too..
