F-Body Spindle on A-Body problem

Thanks for the info, Thats pretty much what I was thinking, but to get them bolted in, the torsion bar bolt is practically on with 4 threads. I have not set the dart back on the ground yet, so I imagine it will push up a bit and need to be adjusted tighter again. I just have not done a disc brake swap or even lower ball joints on an older mopar before.
