as mentioned the reluctor fits tight by itself but still somehow loose. When pin is installed this adds the needed presure to make a tighter fitment, like a preload spring. Usually is better try to fit the reluctor and pin already aligned to the shaft provision for the pin to don't need to match them while pressing down the reluctor.
dunno if my opinion helps or not
Yeah, but not on the big block distributor that I took apart a long time ago. I've got plenty of distributors to see what the issue is.
