I bought the spin-on oil filter adapter.  No where in the directions does it tell what is the proper oil filter part number to use. 

I assume it is the same as the old Ford spin on filter that I have purchased in the past dozens if not hundreds of times.  Vaguely, I remember Fram PH-8???  I went to O'Reillys and their chart does not go back to my old '59 Ford or my old Maverick or Econoline.  I have spent an hour on the internet trying to get the same info with no success.

One more question.  I have a '56 2 dr and I don't see a lot of room for the filter.  Wasn't there a stubby version of the same filter for use in tight places?

Thanks guys, I know I'll get some good answers..

I’ve been using Wix 51515. I like them because they are black. NAPA gold has one too. Same company makes them both. Check it often as there are writeups on the replacements leaking. As I remember the oval went on the top to keep the filter full. As a side note when I start an oil change I stab an ice pick at the bottom corner then drain the oil from the pan. By the time I’m ready for the filter it’s drained and doesn’t make a mess on the block.
My O’Reilys stocks them. We also run them on my sons dirt car and my LSR roadster.
