I have a set of the Mopar A-body [002-003] Super Stock leaf springs on my '67 Valiant. When I installed these 5 years ago, I had to drill out the shackle bushings from 7/8" [A body] to 1" [B/E body] due to the fact that the SS leaf springs rear eye is 1". I used the B/E body shackles, which work perfect for the leaf spring end of the shackles, but the larger B/E shackle will not fit into the rear leaf spring hanger on an A body because they have the 7/8" bushing. I had a hard time trying to drill a 1" hole in a A body bushing with a 7/8" hole. It was hard to keep the hole it in the center. It also doesn't leave as much rubber. My question is, does anyone make an A body rear leaf spring hanger that will accept the larger 1" bushing for use with SS springs? Does anyone make an A body shackle with the 1" hole for use with SS springs? What is the best way to drill out the rubber shackle bushings?
