No need to do it for one part that's just made for testing.
I don't think I understand... sorry. You guys are sure keeping me busy, I wanted to do some more FEA analysis on our rear lower control arm and start on our trailing arm.

My original suggestion was to use a shoulder on the bottom, and a nut on the top of the heim joint. You mentioned some issues that would arise from the cost of keeping the tolerances that design would require. So I thought it might be possible to put an internal thread on the bottom of the shank and use a bolt from the bottom. But that wouldn't allow sufficient bolt stretch to put sufficient tension on the bolt to stop it from turning out. It also wouldn't allow for the use of either a cotter pin or lock wire. And a stack of Belleville washers would eat up all the space I was trying to save, so really it was a stupid suggestion.
