Thats certainly a valid point, but I have no idea of PST's quality control, whether they source multiple vendors for these parts or what so I can't give you a good answer on that.
What I do know is that the ones they took my money for didn't seat properly in my /6 K frame or the V8 K that's in the car now. The original shafts fit great in both K's, the PST ones didn't.
I posted this thread so that if anybody else has in fact had this same problem, they might come forward and then shed some light on the question you posed. I already referenced 1 recent thread that indicates the same problem, so there are at least 2 instances out there. So far.
Perhaps more people would have responded to the recently locked thread if it hadn't been locked so quickly. (Sponsor Vendor censorship??)
I'm not too concerned as this was a few years ago and my car works just fine with the original shafts and stock bushings, but I thought I would offer up my experience to challenge the myth that "contacting PST and talking it all out" was some kind of universal solution.
