I assume from the original post that this transmission was a standard 3 speed (manual) column shift type. Those came in two variants…..the very short rear retainer version (110” wheelbase) and the typical long tail housing version (118” wb). The shorter housing has no bushing where the slip yoke fits. The longer housing would have the regular bushing at the rear end, just in front of the rear oil seal.

Both transmissions used the same 7052 oil seal and it was the fully encased type with the steel shell on all sides. If you have the original seal in there, it can be very difficult to remove. Just using the common seal puller will just tear gaps in the outer shell and you’ll end up pulling only the inner portion out, leaving most of the steel shell. That part is usually rusted into place. I’m not sure how successful you can be in this job without removing the rear housing and working the job with it in a sturdy vice. We normally clamp the housing in the vice and drive the remnants of the old seal out with a long punch. With the longer type housing we use a chisel to punch the seal shell inward, working around the edges of the seal. That’s generally enough to loosen the rusted contact and allow removal of the old seal.

Replacement seals are often just the common type that drive down to the lip of the housing. We stock and sell the original fully steel jacketed seal, and we press it into place with a steel pusher tool in the hydraulic press so that it doesn’t deform.
