I may have to edit this from a pc- sorry about the pic link.

It's obviously not done. But if you see something I should change, let me know.

Probably alot more than the original. I have alot more brackets, fitting, and seam welding to go. I'll weigh the whole car at the end.

I could probably also shave some weight here and there on the lower controls. I made them telescope, and just tacked them, as measuring the original leaf and pirch didn't seem very accurate. Once I know it's straight for sure, then I can go to town on refining it.

I wanted to keep the original frame rails, which caused an unbelievable headache. I also wanted more than two inches of compression. The original rails are about 3" in front of the axle. So the uppers are behind the axles. The lowers are forward - mad caster. But putting the upper above the axle would have left me with very little travel. I'm in PA and the roads are terrible here.

The car is a 78 trans am. The diff and axles, which I'm hoping to test fit next week, are 04 svt mustang with G force axles.

It's really complex to describe it all. I also wanted to fit the original 15x8 snowflake wheels. Which I think I'm getting away with. Also factory rear rotors.

The shocks and springs I'm hoping to mount in the trunk horizontal - pushrods. I also grabbed an electronic rear steering rack from a 300zx, I may implement.

I just dropped in to see what condition, my condition was in...
Hey that is a lot of work.  Looks strong as too.  As you have time update the pics.  I'm getting back to my front suspension.  But still have to finish the rear - slicks are too wide so will build a pushrod coil over.  Will post as I make progress.

DAZE - thanks for keeping the site open!  It is the best single source on the interweb for IRS.

Cheers - Jim

Thanks. Sorry I don't post more, I have alot of projects.

Right now I'm making the spacers that center the spherical bearings in all the mounts and pirches.

I need to fit it together and make sure my toe assembly fits. Not sure if I mentioned the nissan Z32 electric rear rack.

I'll try to post some pics, but progress has been slow. It's not that I'm tired of the project, it's just a huge task for me and it's hard to find the time. I don't think I'll ever go back to a solid axle for the car, but I worry alot about the dimensional accuracy - it's a difficult thing to measure when you want to see near machining numbers.

I should invest in a high quality tram. But playing with projects like this one would leave just about anyone broke.
