I could only find one place anywhere near me selling Baldwins, it's about 11.5 miles away and I just picked up 4 Baldwin B2 fiters there yesterday (Motorcraft FL1A application) for around $6 each. I could buy Wix 3 miles away, but prefer the nice red color Balwin to the boring black Wix. I like to see the filter when I pop the hood or peek under the car.
From the photos above, looks like the can is fairly sturdy thickness of metal. That is something else to measure when you are cutting open filters.
Oh yeah, I love this place that sells Baldwins. It's like a parts store from the 70s, cigarette smoke in the air (don't like cigarettes, but it's the nostalgic effect that got me), etc, not this polished and sterile look of an Advance Auto or other chains. Anybody on the west side of Detoit interested, the place is Great Lakes Truck & Trailer and they have great hours, till 10 pm weekdays and part of Saturday. Google them, they're in Westland Michigan.
