Oil Filter Canister question

[AZ59apacheguy]

So I think I'm going old school with an oil filter setup on my 283 with the canister style filtration. Is there a gasket that goes between the bypass to engine block? I know someone who's got a complete assembly for sale, but it looks like it is missing that gasket. I know there is supposed to be a gasket that goes between the Canister Housing to Engine Block, I just don't know if there is supposed to be one between the Bypass to Engine Block. If there is where can I get one. My internet search only turned up a info on modern spin on filter adapter assemblies. Thanks for your time.
