If by chance the top of your carb is 2 5/8" a paper filter air cleaner assembly off of a mid 60's dodge/chrysler 318 might fit. It fits loosely on the carb on my GMC 302 which has a larger diameter throat than the GMC 228. A 292 carb would probably have a larger throat than a 230 so the dodge AC just might fit.
You can use a large O-ring as a spacer to tighten it up, or cut up an inner tube or piece of plastic.
The one I'm using came off of a car but a truck AC might work. It is the clamp on type which I assume is what you need.
