I believe it is AC #PF-24. There was no Delco on it. I did my research over 10 years ago for my Cutlass and don’t know if the Cutlass used the same oil filter as the Jetfire. You can get a repro sticker on ebay:
I got a white painted filter from WIX. To get the markings off I used rubbing alcohol and some elbow grease which took the markings off without damaging the baked on white paint. Then put the decal on it. However, it does not look like either of the photos Eric posted. I’ve been using this on my car in the absence of any factory or magazine article photos from the period.
