37 standard vs 39 standard steering wheels

[oldandtired]

Can anyone tell me if the 37 standard and 39 standard steering wheels are the same. If not, can they be used interchangeably?

I don't think they are the same,they look the same but I think the difference is in the recessed area for the horn button,it may be bigger or have another reinforcement rib then the 37 which would work if you used the 39 horn button. I am not 100% sure on this but remember when asking the question myself on the old Fordbarn and answer I got. I looked in my 37 book and naturally I note #78 part number but do not see this # carryover to 38-39 standard,but this could be because the 38-39 standard wheel was not black but zephyr beige.

Dean, the 38-39 horn button assembly is about 1/8 of an inch bigger, than the 37. You can get away with using the 37 button, on the 38-39 wheel, and to the untrained eye, looks ok. The 38-39 horn button, on the 37 wheel, will over hang the wheel hub, because of being larger, and looks wrong.....Ed
