i have one for parts that i got for the front diesel housing, and diesel engine.
will see if i can put up some photos.
i took all of the housing off to take the necessary diesel parts off.
the gear set is in tacked as it should be with no housing on it.
looks like any MSG 4 speed sold from 1979 to 1985
it had gear oil in it, so sadly its a parts trans
over on isuzupup site i have a
TON of photos of the 5sp model of the same trans.
other than miner gearing changes, to 1st, 2nd and 3rd and the expanded housing area for 5th gear its the same trans,
unless it has a 4 bolt front bearing retainer.
all 5sp transes have a 6 bolt, 4 sp came with 4 or 6 bolts.
its a long thread, but good info.
