Carb to air filter housing gasket tip

Hi folks.

Not sure if anyone has heard of this cool tip for slant 6's(may work on other engines as well?):

The gasket from a Mopar oil filter(number FE 148) can be pulled from an old filter and put on top of the carb as a gasket between it and the air filter housing. It's the exact same size and works as good as a factory or repro one(may even be thicker and softer?).

Found this out from a local Mopar guy while buying some parts for my 70 Duster.
