I have a 64 panel. Front dropped 3 1/2 with spindle,springs and shocks, rear dropped 4" with springs and shocks. I'm not having a driveline angle problem. (?) I'm not positive if you really "need" to get it back to the same degree that it was at stock ride height. Just don't exceed the recommended angle. ( does 15 degrees sound right? I forget)
At any rate, I've had no evidence in two years of excessive U joint wear or anything else that would indicate a problem as a result of pinion angle. Oops, forgot. I also have a one piece drive shaft too.
