We've played this game a bunch and I'm not going to search down the rabbit hole on my phone........what years had what bushing sizes? I've got a few primary covers and am unloading xb parts, but I'd want to get a measurement to make sure one would suit your needs.
I believe the part numbers are all the same.
ok.....i've never really looked that close at the shift shaft size/bushings on the covers. interesting.
I've got two covers with bushings on the inside measuring approx 13.7 mm
and two covers with no interior bushings; when measured at the exterior they're approx 12.2 mm
