Crazy alignment problems

FWIW, the OP appears to have the early (1970) pitman arm and idler, and matching draglink. The studs point up. The later '73 type pitman arm and idler and their draglink have the studs pointing down. Not sure what the QA1 is setup for.

I know the ball joints/arms are different between early and late. Does anyone know if the offset/angle of the steering arm on the early lower BJ arms angles inward more than the later ones. That could be another source of problems; add that to the list of possible component problems.

OP, did you buy all 1970 idler, pitman, tie rod sleeves, and lower BJ assemblies? Or the lower BJ's from POL? (Which I think are the later ones.)
