Spin on oil filter adapter for 292

[zuburg]

I'm replacing my old 239 Y-block with a 292. I'm moving the external components from the old engine to the new block. I'm surprised I couldn't find any discussions about spin on oil filter adapters using Search so starting one here.

After removing the spin on oil filter, I removed the spin on adapter which consisted of the adapter plate, large seal, insert (threaded piece), and rubber washer (seal?) that fit the insert. In looking at the various parts houses, I can find a complete adapter kit that includes the adapter plate, large seal and insert, but I can't find just the large seal. My questions are: Is the rubber washer for the insert not needed(since I don't see it in the catalogs)? and can you buy just the large seal? I would like to have all new seals on the new engine.

Second, I found that this spin on oil filter adapter does not attach directly to the block, but to what I believe is the original can type filter attachment components which consisted of another plate similar to the adapter plate above and a bushing (part # 6890) that screws into the threads on the block. There was no seal under this first plate that mates directly to the block. Should there be one?

Thanks,
