Unless it is important to you.
I just purchased two new upper control arms for my 70 A66 Challenger from Rock Auto for 142 each. They have new ball joints, and new control arm bushings. I weighed the labor and time involved with cleanup and removal and went with new, stock looking UCA's that are made by Goodmark.
Just a thought. It would be a lot less work and the advantage of new parts.
