Rear spinner bulkhead for 1979 PA-28-161 - confusion over part numbers

[Canuck]

I'm finding it difficult to locate a replacement rear-spinner bulkhead for my 1979 PA-28-161. Starting with the 1979 model year, the part number (according to the manual) is 36757-007 (553-599). When I search for that on Knots4U, Aircraft Spruce, etc, it brings up Piper P/N 36757-003 (553-559) as a result, but I see no indication that's the same thing.

Has anyone here dealt with Piper spinners, 1979 or later?

Thanks for any help,

David
