Just to throw confusion into the fray, here. For you originality
junkies... Remember! the numbers won't match.
It is possible to add an overdrive to an exising NON overdrive
tranny (did it myself). You need an OD output shaft, OD adaptor
plate and, of course, the OD, proper relay and wiring to pull it
off. My OD came out of a TR6 race car and has performed quite well.
the only thing I ran into was I had to get a right angle drive
for the speedo cable.
