Where can I find plugs for a 1938 farmall f12.

wherever plugs are sold use the same plugs for the A and B tractors used as the alike when it comes to spark . ANY NAPA will have them not a big thing

F-12/14 use the large threads, I think they are 7/8 Dia or 22 mm. I use automotive. I think they are 3076. In the past I have used champion w-14

The F12 Instruction Book says .020" to .025".

Plug I have best luck with is the Autolite 3076, I have given up on the champion plugs years ago.

Autolite 3077 used to be THE plug for the F-series, but they quit making them a few years ago. Call around ALL the real car parts stores in your area. You might score a set. If you do, and there's more on the shelf, grab them too. My son and I did that once we heard they were not going to be made anymore, and now we have a life time supply.
