Used Trans and shifter brings a good $500 these days. Looks to be an M20 which is correct for that rear gear. Clutch is another $250 or so, flywheel helps, linkage and cross member another $100 or so, bellhousing looks to have seen better days, I'd get a factory aluminum bell for the street if I was interested, rear is about useless unless it's a posi or someone has a car with nothing under it.
Parted out I'd expect to get maybe $800-$1000 and it may take awhile to move, so that's probably what I would take for the entire thing if someone showed up with cash. Only thing of real value is the trans and shifter, the rest are accesories that need a certain buyer to want it all.
Wanting a Custom fit in an off the rack world.
I don't have time for a job, I just need the money.
