[FC] oil filter

[corvanatics@corvair.org]

   So, I went into the Kragen auto parts store around the corner about a 
month ago, pulled a Fram PH4 oil filter off the shelf (the last, dust-covered 
one), and took it home and put it on my rampside. Today, I went back to the same 
place, and couldn't get a PH4, or anything that replaces it. They couldn't look 
up any equivalent, because their system is set up to look by car model, not 
by part number, and they only go back to 1967.
   My question is; what readily available oil filter takes the place of the 
PH4? Or, do I have to mail order my oil filters?
