I was nervous cause it didn't have the two vertical slots on the inside like i see on other gaskets . But fear not. I put it on and it didn't leak. I didn't need to put any other liquid gasket sealer on it.

Lined up the gasket with the holes and wallah!!

I drove up to Reno, Nevada for Hot August Nights and installed a highway ring and pinion in my 12 bolt for the round trip and used Catapiller form-a-gasket. Did not leak and I wanted to reinstall the 355 gears when I got back. Will buy a couple more.
