if/when I rebuild The Defect III, I'm debating going back to a 3N71B, as the gearbox in it is a 60L four speed and I was drivng that gearbox hard in the original defect and cracked one of the exhaunt mounts off the back of it - it uses the exhaust hanger position to mount the gearbox into the car, and I broke an engine mount in THe Defect too... hover I've notived the 60L 4 speed is starting to not like being put in reverse sometimes, and an thinking it's in the early stages of stuffing up... asnd Celica 5 speeds are a dead option, which leaves the 3N71B...

as for collecting 60L four speed gearboxes.... only ever came across one, and I was actually shoucked when I found out it is an A14/A15 gearbox.... as junior stock cars are supposed to run 56A gearboxes - gearbox is out of a junior stocky 120Y)
