Try classic industries,ames,py. I went to pro touring F-body.com and replaced the leafs on my 72'bird and used the solid metal style pad instead of the rubber one.

LeighP 12-24-2013 02:16 AM

Pro-Touring F-Body. They sell a fitting kit with HD shackles, bushes, J nuts/bolts and the HD replacement U bolts, urethane spring perch pads etc.

I'm sure if you don't want the whole kit, he'd probably split one up for the pieces you need.

Google up his website for contact details.

none of this stuff is OEM stock ,so if thats what you want, I'd hit up the site sponsor or Ames etc.

Only one place to get own style ones. Do a search in the 70-73 section for "spring" using my user name and a couple of threads will come up. I would post a link but I am just learning how to use this new phone of mine.

I think this is the post Norwood is talking about, another dead-on factory reproduced part from him:

Here's a suggested method and how Norwood's spring clamps look on a fresh set of springs.

Dis-assemble the springs. Mark them so the left and right go back together properly.
Keep the rubber inserts under the spring clamps.
wirebrush to bare metal.
push new bushings in.
prime with zinc phosphate primer.
topcoat with OER High solids silver.

plastic spring spacers are available at Classic Industries. I haven't found them at PY or Ames.

Spring clamps are NORWOOD. They are perfect and accept the rubber insert perfect as well.

Good luck and have fun.

Just restoring the original leaf spring from the 72 T/A. Sorry no new Pontiac project but I will be starting on a 68 Dodge Charger soon!

Thanks

Do you have a part number? I could not find them on their website....

165th 12-27-2013 01:30 PM

The Classic Industries part no. for the plastic spring spacers for 4 leafs is K0097. K0098 for 5 leafs.

The reason you may be having a hard time finding it online is it's listed as a '67 ~ '69 part.

It's expensive because they do not sell the plastic parts by themselves, so you have to buy the metal spring clamps too, and then throw them away and use NORWOOD's.

The correct rear shackles for '70 ~ '73 on Classic Industries are also listed as '67 ~ '69 parts but our host has those handy.

spring rebuild
 
I see 165th used wire brush. is there a disadvantage to sand blasting the leaf springs?
by the way your springs look great!

Thanks Brad. Sand blasting is fine if you have access to it. My blaster is across town, and you have to drop off, then return to pick up a day or so later, so I traded elbow grease for the convenience of blasting them. Blast away, but even more reason to need primer, to fill the profile left by the blast media.

Greg - Those springs look great. Where did you get your stencils? Did you make them or are they available somewhere?

Hi Bob, thanks for the compliments. The stencils are commonly found from the Hobby store. Size doesn't matter too much I don't think. Attached are a couple of examples of original stenciled numbers on springs compliments of one of my previous resto's and NJ Steve's springs on the white TA he used to own. The yellowed stencil is significantly smaller than the white one.

The PL and PJ stickers are home made. I'll be glad to send you a set if you'd like.

Attached is a pic of another set I recently finished. I've chose to put the painted stencil in a location towards the rear of the spring that can be a little easier to see when looking in the wheel well just behind the rear tire. It's a little darker and harder to see I think when placed in the front portion of the spring. Not sure if that makes sense.

Side note, this is my first post with large embedded pics included in the post. Thank you to JohnTA1 who recently posted the instructions of how to do this. So much fun!

Thanks, but after all the fluffing of the rear end, what I really want for 2014 is for my car to sit just like yours when it's on the asphalt! :)

Norwood 01-01-2014 06:06 PM

I want it sitting next to mine.....

Gator67 01-01-2014 06:11 PM

I didn't detail my rear end or springs, but after looking at yours, I regret it. I too wish my car would sit down like Norwood's.

Did you use the same OER high solid silver on the axle and brake drums? If so where was it purchased?

Please post the OER part number and the primer part number you have used. Would like to use the same you used..Looked for OER hi solids and all I found was aluminum color?? Appreciate your help..

Call me crazy, it's ok, I've been dealing with these demons for years, but I've always been of the mindset that if the 'Shades of Gray' vary for the different parts, there is a greater character and depth to the completed unit that makes it interesting to look at when taken in with the rest of the underside. I'm certainly not advocating that these particular shades represent the exact color of a bare steel tube or cast iron part or annealed flat bar spring, but it does in my opinion give the assembly character, while being easy to maintain at this level.

The picture in the previous post of the CM-G rear with the assembled springs did have brighter drums originally but I changed that to more of a cast color later, and is now more like these examples of a GY-G rear end.

With that said:

Primer is Tempo A702 Zinc Phosphate primer. Need lots of light coats. No heavy coats or it will never dry... unless you can fit the part in your wife's oven. Found at your local aviation parts house or online.

To get rid of the surface pitting on the steel tubes, glaze coat and/or Evercoat high build primer, sanded smooth

Steel tubes: Seymour Stainless Steel 16-054

Cast iron pumpkin: Eastwood Spray Gray

Brake backing plates: Eastwood Brake Gray

Brake drums: Bill Hirsch Cast Iron High heat primer.... Cooked in the oven for curing and maximum spousal anxiety.

Leaf Springs: OER High solids silver K89580 from Classic Industries or probably found online too.

Polished off with some custom made decals correct for the application and some Quanta inspection paint replicated paint daubs from known original examples.

I hope some of this information is helpful.

I'm never looking underneath my car again

Brewster 01-03-2014 07:24 AM

Those inlet exhaust pipes where originally welded to the muffler and what color are those tank straps black or green?
Ha, Looks great Gregg and love those leaf springs! ;)

Nice catch! Gardner does what he does, but I didn't know that one or I would have tweaked it before the install. Straps black or green??? It's too hard to tell from exposure in this picture, but I don't think I knew that about the straps at the time so probably going to have to say black. :D To the best of my knowledge that car has never surfaced here on these boards since the RM Auction several years ago.

Here's a couple of before pictures that shows why I decided to fluff the rear end and improve the exhaust. This area of the car just wasn't done to the level of the rest of the car. You may have missed the 4 black bolts in the floor pan filling/hiding the holes left behind by the Magna Flow exhaust pipe hanger brackets.

Other than this area and a few other minor spots, the car was awesome, so it was definitely worth the effort.
