Not to hijack this thread but, I think I have a problem too, I run afco rears (da) & well I had one 1.23 - 60' time, then 1.38 to 1.41's now I was under car re plumbing fuel system & noticed the body of my shocks have dents in them? What the hell?, appears I have so much axle wind up they hit the tubes on rear end,.. I have no snubber, no ladder bars, just super stock springs, car is back halved- thanx for any input.
