Re: 1969 GMC.. right off the farm

I think I may be SOL on rebuilding the stock control arms..

Spent some time degreasing them and cleaning them up after grinding out the upper ball joints, but that may end up being a waste of my time once I started working on the cross shafts so that I could replace them.

I was able to get the upper apart pretty easily, but looks like the shaft nuts were cross threaded into the control arms, threads on the inside of the control arms are pretty mashed up and threads on the nuts are essentially gone. Anyone know what size threads these are if I wanted to try to clean up the control arms with a tap?

As for the lowers, they seem like they are fused together.. someone went crazy tightening them the last time it was worked on. Had a huge breaker bar on there with no luck, may try some heat to see if I can at least get them apart.
