There were 2 different filters used on those cars & trucks. The dealer installed ones were AC. The aftermarket was made by Fram. The quickest way to tell the difference is the AC uses a 5/8 wrench on the cover bolt & Fram uses a 7/8 & sometimes has a big wing nut. You must get the right cartridge even though they make replacements for the other brand.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
