J-3 Cowling Air Inlet Cover

[reileyr]

Does anyone have a drawing of Piper p/n 73951? I used one of these covers for years, but let it go with a cub after I switched to flying C-180's. Now I'm back to a cub and want to buy or make another cover. These air inlet cover plates really do help keep oil temperatures higher when flying in snowy conditions.

Reference Piper SB-84 c. The cowl air inlet opening, the first opening under the propeller hub, should be closed. Piper Part 73951 is a cover plate for this opening.
