GM to Mopar trans swap?!
I don't follow used parts much, but it "seems to me" as many people that have "gone to" 4 speeds, that some of these 3 speeds should be laying around. You might want to put an ad in our "want ad" section either for parts or complete 3 speed
Also, what year / model we working n?
This a full syncro 3 speed or non syncro into 1st gear? Different gearboxes
