The rear governor housing MUST be removed, for any repair.

Your current housing will probably need to be "rebushed" along with being "resealed" and possibly need a new throttle shaft, too.{if there is wear or groove on old throttle shaft}

The last, I knew, you could buy a "reman 3208 governor rear housing that already had a new bushing inside of it (and maybe the seal might have been installed already ,too = I can't remember, exactly)

It takes special jig, and reamer/s (2), to install a new bushing in an older 3208 governor housing that has never had a bushing before (ream out aluminum to insert a new bushing) = the new bushing is a hard material and that removes the play in the shaft and thus a new lip seal will last a long time.

There is also, an update for 2 longer mounting bolts, with 2 spacers. These bolt the rear injection pump to engine block = longer bolts = more bolt stretch; that was a common area for bolts to come loose and wear on the flat surface of the engine block. When this happens, it "rounds the block's mating area", and you go to tighten down new housing, on a "rounded surface" then it breaks the new flat rear governor aluminum housing (usually one ear breaks off, sometimes it cracks the whole housing and leaks)

Bottomline: if you find the injection pump's rear 2 bolts loose, you really need to examine the flat mating surface, of the engine block, to insure it is still "Flat".

Here's some photos/diagrams from internet:
