Air Cleaner question

Gentlemen,

Does anyone know what size thread the threaded rod that the wing nut fits on when mounting the air cleaner on an '81 300.

Stock carb.

It is NOT 1/4-20.

i have checked my 85, my 79 and the other 3 carbs i have in the garage. they all came out to 1/4-20 thread. is it possible that either A) the hole has been worn beyond limits? B) the internal threaded piece thats fastened to the top of the carb was modded or changed out for a different size thread?
is it larger or smaller than 1/4 inch? might be a couple things you could play with from the hardware store to make it work.
