Anyone tell me the exact dimentions:
- I.D.
- O.D.
- Thickness

For the O-ring that goes between the Oil Coolier Adapter and the Oil Pump Housing.

Thanks

The exact size I dont know but it doesnt have to be super precise as the GM ones are thinner than the ones the vendors sell which are beefier. If making them or something go by the bigger ones!

I did a search, and found some info.

#144 is what was said...2-1/2" I.D. x 2-11/16 O.D. (3/32 thick).

But not sure is that is stock, or the thicker one I've been hearing about.
So I grabbed other "close" sizes to fool with.

Ah yes.
I use #145's[fits perfect-just put one on Fubar's car].
Get it in Viton.
It's about .010" thicker than the stocker.
