Since I just converted to a 32 spline 465/205, I had the shifter off. As a matter of fact, I have one out of the '74 465 and the '85 465.
I've seen the "o-rings" referenced before, but never removed the end piece on the shifter, the one held in with the roll pin. Decided to pop both apart because of the "slop", and see if there was anything I could do about it.
Both of the shifters are identical in regards to that piece held in with the roll pin. There are apparently two of "o-rings" that are supposed to be in there, the '74 had nothing, the '85 did, but whatever GM used just crumbled and fell out.
From what I could tell of the pieces that were there, these were not o-rings. There are grooves both in the shifter itself and the removable piece, where the "ring" seats, but the "ring" appeared to be square cut, like a governor cover seal if anyone knows what those look like.
I checked the '85-88 parts manual, apparently thats not a "service item", as it's not shown with the shifter. I was at Napa and bought a couple of o-rings that fit, but they are not thick enough to make a tighter seat. Any known sources for the actual right piece? From Napa's o-ring chart, it didn't look like you could get the same ID o-ring, with a larger OD.
IMO these are there for nothing other than vibration/noise cancellation, BUT if they were fairly solid and a tight fit, shift feel would be at least a bit better, it couldn't get worse.
Would be interesting to have a before/after on this. I know it can be welded up, but I'd prefer to try "stock" before taking that measure.
