I might have something you're interested in, I don't know. On my gallery listing, it shows what I used to have under the hood. This has since been replaced with a factory setup.
Sitting now on my shop floor is an oil bath air filter that fits a Rochester B carb. It has flat "pie pan" cover. I don't think the pie pan originally went with the bath, but it fits quite nicely. I don't know what year any of it is.
You don't mention what year is your truck. I found a perfect match for my '58 from Jimbo59. He parts out trucks and sells them by the piece on eBay. I got a great assembly from him. You can look him up, or try posting to the Parts Wanted section after looking through the Parts for Sale section.
Let me know if you want mine. No cost except shipping. Comes with the element.
