Howe Racing offers take-apart Chrysler-type ball joints in various lengths; 
the studs are offered separately. You need the correct 7 degree taper studs 
on whatever ball joints you use and Chrysler screw-in ball joints are the 
correct taper for Fords/Panteras. Never checked Mangustas. IMHO, its far 
easier to adjust the position of the threading in a custom a-arm recepticle than 
to change the taper from GM screw-ins (the only other choice). On our '72, 
I used Chrysler non-take-apart upper ball joints at all 6 positions, but 
shortened the studs to Pantera length. With slow, light cuts (I used a tool 
post grinder), Chrysler ball joint studs can be center-drilled, shortened & 
rethreaded on a lathe, as long as its never been lubed. Once lube is pumped in, 
the stud will shift around far too easily. 
See April '08 POCA News with photos: I cut the threads off Chrysler 
screw-in ball joint bodies and pressed them in place 'cause the available (very 
expensive!) tap will cut full depth threads that are rattly-loose on the 
half-height threads of the ball joint bodies, and the tap seemed to thin the stock 
upper rear a-arm recepticle too much for good strength. So far (4 yrs now) 
no problems. Good luck, Bill- J DeRyke
