Flipper;
This is the same 4-spd trans that goes in the GT, the only difference is where the shifter actually attaches. The on in your pics looks to be straight up, and that indicates it came out of a Kadett/Manta/Sportwagon/Sedan, a GT has it canted to the side, as the motor is canted too, to comensate for the low hood clearence. But, it's easy enought to swap the pieces, takes about 10 minutes to do the swap and with the correct GT piece in there, it'll bolt right in, other than that, the shifter would lay too far over to one side.
