Well i have 2 oddball boxes the first one is in my ke70 4ag. I was under the impression that ae86 and 71 t50 are the only ones with the correct splines and bellhousings for 4ag and 4ac style.

THis box i have in the car everything is correct, splines, 5 speed, shifter but had a different bellhousing and had the origional seals in ti so hasnt been changed, drivers side clutch????? WHere did it come from????

THe other one i have

splines are correct for 86/71 not sure if its 5 or 4 speed, bellhousing is not 4a, the 4 bolt flange that holds the throwout bearing is a different shape and the shifter provision in the selector shaft has a diameter smaller hole in it than your usual 4a shifter???? WTF is that fom???
