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 but one is not oval. Thanks for any help you can give me.
