A couple years ago I bought some oil filters off E-Bay, they were "suppose" to be Baldwin filters for the 350/455 Buick. They're NOT Baldwin, but Im not sure what they are, they are not Fram, and they all fit the pump fine. The orange one is HUGE compared to an AC PF 24. The box for the big orange on says Gambles, sounds like a dept, store from down south back in the day
