O Ring size, please

[clhyer]

I am changing the speedometer pinion gear to get more accurate mph readings. Anyone know what size the O ring is on the housing? There was some leakage, so I may as well get this done while I have it opened up.
Oh yes, it is a 904 tranny.
Thanks,
C

Try your local tranny shop. I buy all my tranny parts at a local shop. They sell me the parts at lower prices than the auto part stores. You also should replace the small shaft seal.
