I want to put in my blocker plate. I'm looking for another gasket but keep getting the question of "which one" Apparently there are 3 of them. Anybody have a part #
Thanks,
Todd

I put mine on without a second gasket and I have no leaks.

same here, you dont need another gasket. no leaks. install the plate with the factory gasket toward the firewall and the plate towards the front of the truck and it will be fine.

worked well for me, just don't do like i did and have the ratchet in the tighten mode and bang up your nuckles when it pops off.

Thanks for the replies

Try part number 97328807 for the GM gasket. It was originally posted by CntrlCalDmax on 10/14/2004 as post number 561. Here is the link:

I believe the retail price is around eight and a half bucks.
