Subject: Leaky 1200 speedometer gear

Oldrunner from Southern California. Owned our 1200 for 36 years. Installed a rebuilt A14 with Web 36/32, two years ago. Great difference in spite of an AT which never gave us any issues. But now an auxiliary part has.
The speedometer sleeve is leaking. New cable purchased. Took it to a Trans shop who installed a used sleeve (Bullet) with its pinion gear (20 teeth). Still leaks. Will get back to the leak issue. But first, under "Speedometer Gear" it says I should use a 17 teeth gear if I have 155X12 tires, which I do and if the differential is stock, which it is. My speedometer appears to show the correct speed. Haven't really checked it though. So my first question is: should I continue to use the 20 teeth pinion gear? Back to the leak issue.
2nd question: Could the leak be coming from one or both of the 2 O rings inside the sleeve? And if so, can thy be replaced or do you advise purchasing another sleeve?
Since a sleeve and its gear are hard to replace, especially for a 1200AT (manuals are available) would one off a Z car fit? If so from a manual or AT, how many teeth and year, 240,60,80?
Will consider any suggestions.
Thank you
