Tranny ID help needed!

[GMCLegacy]

i have a 4wd SM420 in the garage, it has one PTO output on the driverside, and reveres is down to the left.
But i need a 2wd...
anyway, i know a guy that has a 2wd SM420 (he thinks) in his 3/4 ton 67 longbed stepside that he was wanting to trade/sell. looking at his tranny, it has a PTO output on the passanger side, and unfortunatly the shift forks where froze and i could not run though the gears.

what manual trannies did they put in 67 chevy pickups.

my thought they put the SM420's in correct? are there any other 2wd transmissions they put in those pickups?

does anyone have a 2wd 420 they can check to make sure the PTO output is on the driveside?

what tranny does this other one sound like?

thanks
later
