Upper Control Arm Crack

i'm replacing. the ball joint threads are shot as well. thinking i'll maybe sell these if anyone interested. I'll post pics later. They have 2 nice coats of primer on them now.

Just asking! If the ball joint threads are shot, also, why in the world would anyone want to buy them?
UCA's for your car are dirt cheap, used.
Anything from 1962-72 fits, works.
