The standard filter for 68 to 72 (at least) is an AC Delco PF25, the longer filter (1/2 qt more capacity) is an PF35 and the long filter with the anti-drainback valve is PF1218. If you're using Fram, STP, Purolator, etc, you'll have to x-ref those numbers.
The AC part nos. may have been superceded but any good parts store x-ref book should get you to their brand. Dale McIntosh I've stopped 3,387 spam messages. You can too! One month FREE spam protection at http://www.cloudmark.com/spamnetsig/
