Type 3 gearbox

[frankie boy]

I would stay with the type 9. Very early sierra’s can with the 4 speed type 3 as did my first project. You will mostly drive around in third gear with the type 9 but will be comfortable on the motor way in fifth gear at 80 up to 120. It’s a good strong box. Was thing why i did fit the type 3. The type 3 clutch are come out at 90 degrees and hits the transmission tunel unlike the type nine at 45 degrees.
