Newb advice

Ok, let me see if I can post pics. Be patient.
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.
