Original Oil Filter

Q: Original Oil Filter

Wanted to know if anyone knew anything about PF23 AC oil filters. I ran across a NOS one that is white with blue stripes and red AC logo on it. On the box the only application listed is 1967 Pontiac V-8. I am sure it was superceded by the PF24. The 1967 Firebird parts manual supplement that is dated effective February 1967 lists only the PF24, the 72 Pontiac master parts catalog lists all PF24, no PF23 for anything. What would be correct for a 1967 bird built third week in May if it just rolled off the assembly line????

A: Just curious as to why you want an original oil filter, be it a PF-23 or PF-24. To be 100% correct as it was at the showroom fresh off the assembly line it would be painted PMD metallic blue. The AC identity would be obscured. There are lots of reproduction AC filters out there. Go to K Mart buy the latest AC filter and paint it PMD metallic blue. I wouldnt run an 30 year old design filter on a $20K restored car anyway. No more than using 30 year old oil. Just trying to save an engine an some money.
