Stumbled upon this looking for some stuff....dunno anything about this but figured maybe it's a big deal or useful to someone doing a resto. https://milwaukee.craigslist.org/pts/d/stevens-point-original-ac-pf-7-oil/7158697652.html Original AC PF 7 Oil Filter with Nut. Olds 442, Pontiac GTO, Buick GS. - $80 (Stevens Point) image 4 of 4 © craigslist - Map data © OpenStreetMap This is an original, in-box, AC PF 7 oil filter. It has the nut on the top (or bottom, I guess), that some guys like on their high point restorations. It has that very period look, compared to a non-nut PF 7. For 1959 to 1965 BUICK, OLDSMOBILE, PONTIAC, and CADILLAC. This filter is in very good condition, with no paint issues. The price is $80. If needed, I can carefully pack and ship this filter for a reasonable amount. Please email, or call 715-341-6188, if you have questions. 1960, 1961, 1962, 1963, 1964
