Steve,
I have some photos of both the 'acorn' bottom of the gear lever as well as the extension rod that operates the gear selectors. Let me know if you want them; if so, let me have your email address and I'll sent them.
Regarding dimensions, the overall length of the 'acorn' on my lever is 20.05mm, the overall diameter 20.05mm and the small end of the acorn 10.06mm. By the way, the 'acorn' on my lever is made from ferrous metal, not plastic.
The 'acorn' fits into the extension rod and this has a 20.40mm plastic/nylon bush pressed into the extension rod. Allow for a little wear on the parts that I have measured; after all, they're 40 years old!
I understand that the four speed gearboxes fitted to the Rover P6 3500 were essentially of similar design to those of the P6 2000 and 2200 four cylinder cars; they were 'beefed up' in a number of areas. It's possible that the gear lever extension was shared between the Rover 3500 and 2000/2200 cars. Speculation on my part.
Hope this helps. Regards, David.
