The Ford Barn

Guys, The windshield frame is without a doubt an authentic frame and has always been with this truck, well since at least 1965 or so. It has NOT been modified in any way.
Wiper motor has been gone since placing this truck in storage, mid 1960's.
I am just now putting this truck together and find the wiper motors I have, have different center-to-center mounting than the windshield frame will agree with.
The motors I have, have a center-to-center distance of approximately 4 3/4".
The windshield frame I have, has a center-to-center distance of
approximately 5".
If it matters, I figure this truck to be a mid-production, 1931.

Thanks guys.

This link is all I have to go by but it doesn't seem to have any mounting ear distances. The commercial for 1931 would have likely had one of the closed car Trico vacuum wipers. At least the common closed car types are listed.

My '31 CCPU uses the driver for a windshield wiper motor. There is no provision for an alternate powered motor.

Ford used the manual hand operated wipers for all the earlier commercial vehicles but that changed in 1931. Whether the Trico types were optional or standard, I don't know. Ford started producing the Budd cab commercials later into 1931 so this further adds to the possibilities. I don't have the judging standards so I'm limited on useful resources there.

I measured my 1931 closed cab and the wiper motor mounting
holes are 4 3/4" center to center.

From the information in the MAFCA pdf it seems that it likely used the outside mount type with plain black finish & nickle knob that mounts curved side down (TR-C1A). This would work with the sun visor or at least it should. Maybe someone else could confirm that or confirm one of the others.

Pretend it is a Tudor.

Guys, I want to thank you all once again.
My current thinking / plan is to introduce one more hole in the frame so my motor will mount.
The chart that BobC posted makes it appear that's what is absent.
