Oil Filter Canister Seal Question

[cshanek]

Hello,

I recently spent some time with a coworker rebuilding my 283 (pic below) for my 1964 C20.

I noticed that I had a minor oil leak from my oil filter canister (pics below), which has a weird, spring-loaded bolt assembly. I could not figure out how to disassemble it or replace the rubber ring/seal, and I honestly had difficulty finding a diagram or replacement for this particular flavor. A lot of the filter canisters I reviewed were screw-on. Any thoughts or help would be appreciated.
