What Products are Needed in the A-body world?

When you get around to making Upper Control Arms, get rid of that nuisance mopar ball joint. Put a decent sized heim joint in it's place.

There is little load on that upper joint. With an actual camber adjustment in that location you can set the caster & still adjust the camber.

The only reason for the tapered hole in the spindle is to grip the shank so you can tighten the nut. A through bolt & heim joint would be just fine, and much faster to make a camber adjustment at the track.

In fact, I would be happy with arms that simply had the proper caster built in with rubber bushings & stock bolts on the inner - and a camber adjust on the outer with no more screwed in ball joint.
