Paul,
I had finally found a repair shop nearby who said he could help me out. After receiving the part, supposedly for a late gearbox w/out OD, I found out that the gear in my gearbox did not match the one he sent. He sent one with 26 teeth and mine has 30 and is slightly larger diameter.
Your reference to Brit Vic, page 132, is for an earlier gearbox with OD. Is it your feeling that this pinion will match the one in my gearbox?
