273 Commando Air Cleaners and Valve Covers

If your going to use a newer carb, the air cleaner base won't fit.

I had an old small "Universal" 10 inch {Or maybe it was 9 inch?}
ai cleaner, and used the base from that.

For the air filter, I drove the car to Advance Auto Parts store,
and took the base, and top inside. I found a filter that fit,
on the second try. {Fit some kind of Ford by the box description}

My top, I bought on Ebay, it was from a Slant 6 engine;
someone had had it chromed over the years past. :)
