My First Mopar- 1966 Barracuda project
Flip the spring hangers before welding the spring perches to your axle. The flipped spring hangers really mess up the pinion angle.
I tried it on my dart. I ended up putting it back to stock and used 1" blocks. The angle was really bad and that was with a stock rear end. I wasn't about to cut the perches off to start over.
