I have a 37 chevy i am restoring and a previous owner welded on a front suspension that i am now having trouble identifying. The spindles do have casting numbers 459755 and 459756. Note that the upper control arm shaft has a slight bend and the ball joint is bolted in (looks as if they may have been riveted in and previous owner bolted new ones into same holes)..the lowers have riveted in ball joints and it looks as if the bushing holes may be different sizes. I am leaning towards Chevelle because I believe I have concluded the rear end to be a 72 Chevelle (casting number 3969277 - 10 Bolt) I have the pics on the following web page. (scroll through page for all the pics I posted more today.) Thanks for any help you can give me.

Nope, not Chevelle.

I wish I could be of more help, but it's definitely not an A-body GM.
