My Notes:

The car was sold to me 15 years ago with the representation that it had M S X for gears 3, 4 and 5

Actually, yesterday, we discovered what was in there was MSV. Thus 5 gear was way too short — only 8 mph difference from 4th. Stampings on the 5th gear are confusing so that the mistake may not have been deliberate. But it is definitely a V as it had 26 teeth.

We are going to change to M, V, ZD. ZD has 34 teeth.

The set up of V to ZD for 4th and 5th is the stock set up so it should be a good spread and about 1,000 RPM slower at 70 MPH from the prior set up.

Second gear is F 18:34 which is correct

Rebuild needs: first gear synchro. Third gear, synchro. Fourth gear synchro. In summary, we’ll buy five synchros. 1st/reverse operating sleeve. Pinion shaft bearing in the intermediate plate
