I've got a Muncie 4 speed trans. I've identified it's a '65-'67 trans. I think. It has a 3885010 main case, a 3857584 tail shaft case, and a 3884685 side cover with 3/8 fine thread male studs(to attach the shifter rods). I've also identified the "circles" on each case. It has 'NO' notches on the shaft and no drain plug(Did all M22's have a drain plug??)It has the letters/numbers on stamped on bearing retainer(piece inbetween the main case & the tail shaft case) "PO307". What is that??(rebuilder's #?).
Then stamped on the main case, bigger numbers/letters(looks like from GM--like stamping the factory would do) "6Z142867"(or "1" maybe the last number instead of "7"). Is that some sort of factory number?? Thought I'd ask before pulling the side cover and count gears. Should inspect anyway. Help Please.
