Hi Bill, you didn't mention which bellhousing and which gearbox you
have, so I'll go worst case of a TR4 gearbox into a TR3 frame & bellhousing:
The TR4 Transmission will bolt up to a TR3 bell housing . You will need
the next length longer bolts at the bottom of the bell housing because
the lip on the TR4 transmission is wider then on the TR3 transmission.
This will also require you to readjust the clutch slave cylinder rod.
The transmission mounting holes will be slightly to the rear of the
cross member mounting holes. This can be corrected by elongating the
mounting holes on the bracket where it mounts to the transmission and
where the bracket mounts to the frame.
You can use a TR3 drive shaft without modifications. By the way, the
transmission goes in easier if the drive shaft is completely removed.
Otherwise it gets in the way of lining up the transmission for
installation. Since the TR4 shift lever is different, use the TR3 shift
lever. It is a direct fit.

My TR3 got that exact conversion last July. I love it!!!! Steers a lot
better with a lot less effort. I would never go back.
