Dimensions For Speedo gear housing seal?

[Corrupt_Reverend]

Anybody know the o-ring size for the speedometer gear housing seal? (The big, outer one)

Nobody local has the part and I was hoping I could just get a correctly sized o-ring to do the job short-term.

go to your local tranny shop or hardware store.

That's the plan, but the old one is in two pieces. Was hoping to get the size to avoid eye-balling. I guess it's not all the critical though now that I think about it.
