68Valiant: Did you drill your hole for the rear shackle any lower or is it at the stock height?? Also, did you use stock shackles?68Valiant said:mopardad,
I moved my springs rearward 1.75" at the same time I moved them inboard on my 1972 Plymouth Scamp. I had no adverse problems from this.
I believe any more than that you will hit the rear cross frame rail at rear bumper with your shackel.
