Hey all - looking to do the same thing for my car this season to fix a few wear issues (and "upgrade" the rear cradle too while I'm at it). From research it seems our rod ends are a loader slot design, but I could be wrong there. I didn't see it posted, so the total count I came to is:
1/2-20, 1/2 ball - 8 RH thread (all front)
3/4-16, 5/8 ball - 4 RH thread (all front)
5/8-18, 5/8 ball - 8 RH thread, 2 LH thread (all rear)
I found a helpful guide for a few bearing comparisons. Looks like those QA1 X series have a few cross overs too:

I guess I have 2 big questions all this brought to mind:
1) What did you guys end up getting/How are they holding up? There's so many options out there, some first hand experience is always appreciated.
2) Do we know the supplier/construction of the original set? Would be interesting to understand specs of those compared to what I've been looking up.
