Ball joint stud angle?

[MIKE67]

COMMON TAPERS ARE:



1:6, 2” PER FOOT, 9.46 DEGREES = USE 10 DEGREE. MOST COMMON “METRIC” AND CHRYSLER.

1:8, 1 1/2” PER FOOT, 7 1/8 DEGREES = USE 7 DEGREE. MOST COMMON.

Speedway Motors have reamers by two manufacturers in each angle. There are other suppliers.
I am currently debating a similar issue. I want to use the Chrysler large lower ball joint, but spindles to fit aren't available.
