Classic/Antique Car Repair: oil filter, ac delco oil filter, john deere tractors

Question
I am looking AC Delco oil filter PF352 for my 1932 Ahrens Fox fire truck.  I have tried more than 30 auto supply places in Los Angeles, none have them or can order them.  Any ideas?

Answer
This filter is still used by some models of John Deere tractors (the 350 for one).  You can order it from a John Deere tractor parts place under their part number, which is
AR26350. One source is Coastline Equipment, in LA.
