Rear Coil overs
I know that a few have done this mod, and since I will be pulling the body off I thought this would be a good time to approach this project. I did a search but all I came up with was info on the front. Can any
one point me in the right direction for the mounts I will need for the rears??
Also has any one ever made their own control arms for the front???
Thanks in advance,

Some one sent me a pic that showed roughly how they mounted the rears. There was a tall reinforced bracket coming up from the rear of the TAs as the lower shock mount with just ears, I believe for the top. I didn't get into clearance issues. Now I can't remember who it was. I hope they will see this and chime in!
Do you know any one who has made their own control arms for the front???
Trying to save as much cash on this mod as poss.

Oh yeah, about the control arms. There's too many good after makets available to worry about it...VB&P, Speed Direct's aluminum uppers, Jim Meyer racing, there's more but I can't think of em all. If you really want to make them your self use the factory arms to get dimentions, make a plate to bolt the ball joint to, weld it to tubing with threaded ends for some rod ends. You will probably have to use high misalignment rod ends. Add some extra pieces to the lowers for spring/shock mounts, a bump stop, and your bassically done. Just make them STRONG, your life depends on it. You can get most every thing you need from chassisshop.com

Front Arms
SLY,
What is your goal for those front a-arms? Lighter wt, better front end geometry or just cool looks?
You can cut the senter out of a stock arm to make it lighter.
You could look at the conversions that adapt later model aluminum arms to a C3.
I had a set on my old GT-1 car that were modified for lighter wt. and to help clearance for front coil overs. They cut the center out of the arm, welded in tubular front and rear pieces, and manufactured the frame attach bushing area. They were cheap, light, and ugly. But they worked.

Hey Norval, did you put that system together or is it available?
Sly, I hope you at least take a good look at whats available aftermarket, you can pick some good stuff up cheap. I think most on here have learned hard lessons about fabricateing. If you are truely good at it, bless you, few of us really are. If not key components and assemblies that have some experience and engineering behind them save headaches and money.

We do it all from stock including control arms and complete frames. Sideways mounted coil overs dont excite me. Put a 9 in. Ford in it with coil overs and a 4 link. If you can make control arms, a narrowed Ford rear wouldn`t be a problem.

Norval and TT both designed and built their custom rear coilover setups. Both are different in design and both members are gifted with knowledge and a welder.
Norval used a trailing arm, TT built his own rear control arm A frames.
Both very
What is that speeddirect rear system going for? I can't imagine its under 2k. They are rediculous with their prices. Cool design though, kudos to them for thinking outside the box.
I knew it was is the design phase, didn't know it was released to the public. Wonder how it performed in their test car.

Hi Norval, Welcome back I hear you were on vacation. Or do you say Holiday in Canada?
Anyway...How much work am I looking at to do this mod.
The rears are what I am going to focus on at this time.
Did you just mount the shock on the lower factory mount and then fab some ears for the top?
Do you mount the shock at full extension?
Thanks for any help, and I haven't been able to do much on the trans swap due to the cold,but I'm ready to go at any time. Bernie has been helping alot!!!

The shock must be the 5 inch travel shock, the 7 inch will not fit. This 5 inches gives you 7 inches of wheel travel.
The stock top mount is in the right location but I cut it off and made a much beefier one but welded it right back in the stock location.
I then made bottom mounts, I could take good pictures of it now with the car on blocks and the wheels off.
I welded this mount to the trailing arm infront of the 1/2 shafts. I used nothing from the stock lower shock mount.
If you need pictures I can do that this weekend.
I then used 450 pound springs which are still soft in this location
