John, if you have a halfway decent NAPA store near you, see if they can look up air filters for you by size.

The one near me actually has some paper catalogs that the woman who works there flipped through to find various filters by height and diameter. She's old and has been working their for a long time. She also knows how to read.

I'm sure there's a filter of similar size to your pancake stack.
