Yeah, it's perfectly straight. One side went in fine, the other one went in several turns, then bound up quickly. The only reason I think I will need another drag link is because I'm pretty sure the TRE that bound up won't be coming out!
Ah....yep, that can happen. Not that it matters at this point since the end is basically welded in there, but that can be caused something as simple as a chip left over from tapping it--if it's stuck in the threads, it can cause enough hate and discontent to get the threads to gall/seize and make a mad Greg out of you.
