As far as I know Chrysler Corp used the PH8A size oil filter on all its motors, 6 and V-8, throughout the 60s and into the 70s, switching at some point to the shorter PH43, to save a couple of cents I suppose. Still later, the company used some even shorter/smaller filters that fit the same flange, but I found out nearly 20 years ago that the PH8A would even replace the midget filter on my 2.2 four cylinder. It's what I now use on my 94 Ram truck. I usually change my own oil, but occasionally save time by letting Super Lube or the like do it. One time, the changer saw the filter on my small block and exclaimed, "He's got a Mustang oil filter on this Barracuda!" (5 liter Mustangs also use the PH8A). It took me a few moments to convince him and the manager that I wasn't running the wrong filter. Another time/plce I took a 1966 Barracuda Slant 6. Their listing showed the correct replacement filter being a PH43 and they refused to use a PH8A unless I signed a waiver of liability. The point of all this is that the parts book listings will sometimes reference to a later smaller size filter that will fit but would not have been used by the company before sometime in the 70s. I use the bigger PH8A size on everything I own except for my 56 Plymouth which uses a canister type oil filter.

Hi All, I seem to be finding all different numbers listed for sealed canister-type oil filters for: 1958 Plymouth 350 1959 DeSoto 361 The one that pops up the most seems to be cross-referenceable to a Fram PH8A, but I find several other variations out there. Do any of you use the PH8A on your cars? Is it a valid replacement? -Dave
