I just discovered this on my 67 GMC (leafs). At somepoint someone changed the 12 bolt axle and welded the perches on centered off the pinion. my entire axle is over to the driver side by ~2".
Solution: Cheat the axle over 1/2" or so with the track bar or clearance the crossmember if you're worried about it hitting. I would have no less than 1/4" clearance.

This is correct, after checking with a buddy and looking his truck the rear end is off to the right side he has the two piece drive shaft. The one piece drive shaft tents to make it look worse. the engine wasn't centered in the pic so it is better than the pic, I will look into again once the body is back on. I will post more pics at that tome. The X measurements are around 1/8 inch of each other . So I will let everyone know how it turns out. Thanks everyone. for all the help
