My old pilot shaft went in by hand no resistance and you can move it laterally in other words its not snug in the bushing. I noticed the taper was longer on the PST shaft and a little larger.
I had that EXACT problem with those shafts when I tried them a few years back. They wouldn't properly bottom out in either of my 2 K frames (the /6 unit in the car or the V8 unit on deck at the time) because they were too big to go all the way in, even with major reefing on the nut. I gave up before I wrecked something. Unfortunately PST couldn't comprehend what I was talking about (the shafts being NFG).
I asked for a refund but after 8 months of runaround, I just returned them in exchange for a couple of fender covers and used my original shafts with no further problems.
