They are the same military junior filter as used on the M38A1. Try NAPA 1010, although I believe the NAPA1100 is technically the correct one.
If you want to convert those numbers to Wix, just add a 5 to the front. Amazon carries the WIX filters.....$20.56 and you don't have to leave your house, otherwise NAPA is $22.68 full retail or $9.41 trade price.
