the electric drill cut a groove for the arm. I have had 4 or more
1939's that I thought needed a new clutch and this solved the
problem. Also the 7527 rubber bumper should sit in a recess in
the wood. If it don't go in the recess that can be a problem also.

GM, What you describe would hinder the return of the pedal - not cause too much free play.
My gut still tells me the issue the original poster has is wear in numerous pivot places.
