Wheel hop in REVERSE?

He did say the best he got it was with tranny -2.7 down and pinion -1 down and when shimming pinion up it go worse. DUH! Also said he would try shinning the tranny up a degree or so, but says he can’t. Then he has to have the wrong motor mounts to mage it that far outta wack or a broken mount. Does this have factory mounts or home made mounts?. I find it hard to believe u never had an issue with the auto. What tranny is this? Is it an A body tranny? Was it a V8 car or a 6 car to start with? Kim
