IDK, I think I got it off Amazon. I remember it didn't cost much, and my big issue with it was it was missing an anti-drainback valve. My guess is it was probably the truck filter instead on the shorter LS1 filter as I always ran the longer filter on my LS1. Pretty sure it was an ACDelco Professional filter. Even though you technically might not need an anti-drainback valve on a hanging filter, I just didn't like not having it. The filter likely would of work fine, but it just didn't seem as beefy or well constructed as any other filters I used on the car. (Mobile, RP, WIX, WIX XP, Baldwin, Fram Ultra Synthetic) I ended up change my oil very early just because I just didn't like the filter.
From what I've read the PF48 is the same size with the same thread as the PF64, but the PF64 has a better/heavier build quality, with like double the weight of the PF48, but I think the PF48 only has like a 14 PSI bypass. I was very impressed with the construction of the PF64 and have no issues running it.
