My take, turn the shock a quarter turn & weld 4 tabs on the upper shock tube to locate them with a through-bolt going the "correct" way. A bracket made to go in some of the lower holes doing the same thing. This way, you are not altering the ideal pinion angle to make up for some other out of place item. I made a set just like I described for a friends car with the same set-up. It was off-set top to bottom compared to the holes so it could go the the top two holes or the bottom, or flipped over & be even lower. Lorne

Totally agree. As the suspension cycles the current shock mounting bolts will change their angle relative to the shock. This will put strain on the shock bushings and wear them out faster.
