Taken from GVR4 forums.
I was rebuilding one w5fm332 mitsu transmission and founded pretty interesting stuff:
1.86 ratio fifth gear
3-4 double sychros was same size as 1-2 synchros (i think didnt measure yet)
I hope this helps some of you local trans builders, the 5th might be nice for the street car guys.
I believe I have this trans laying around outside.
