Windshield Wiper

[Pete2125]

Hello everyone. New member here looking for some windshield wiper advise. Let me apologize in advance for what may be a lengthy post.

For info purposes I just bought a 1930 Fordor Sedan, briggs body, early '30 has the oval speedo.

Well this car didn't have a windshield wiper installed on it when I got it, I assume it was removed at some point. Well I don't really intend on driving in the rain but I live in FL and we do get sudden unexpected rain here, so I figure it's a safety issue not to have one. I did some preliminary reseach and from what I found I was under the impression that my car originally took a Vacuum wiper motor. (My Dad's early '30 Coupe does take a vacuum motor.) So I got a trico vacuum motor off ebay from a guy that just hot rodded his 1930. Well to make a long story short it doesn't seem to fit.

There seems to be problems with the hole alignment. Firstly, in my windshield frame there are 6 holes drilled. (My Dad's car is 1000 miles away and he doesn't use internet or cell phone so I can't look at his.) Three of these holes are large diameter 3/8"-7/16" or something like that (didn't measure.) Three are smaller 1/8" or so. The middle large diameter hole is where I would think the operating lever for the motor would go, but it's just slightly out of line with the notch in the upper cross bar where the windshield frame mounts. Don't think this is such a big deal, could probably make it work, but the other holes are way off.

If you hold the wiper motor up to the windshield frame two of the smaller holes that line up best for the attachement screws (they also don't line up with the wiper motor) would center the wiper arm shaft on the notch that goes through into the car and the control would be behind the cross member. Obviously this isn't correct. If you move the motor over so the operation control is centered on the notch in the cross memeber no holes line up at all. There also isn't a hole drilled in the frame towards the passenger side where the vacuum tube would presumably exit the frame to hook to the motor.

Could this windshield frame possibly be for an electric motor? Wether vacuum or electric why are there 6 holes drilled? I could understand 4, one for the control one for the tubing or wire and two for anchor. I've attached pictures and just due to lighting and glare marked the picture with editor for easy identificaton of the smaller hole locations.

I wouldn't be surprised if this is just a case of someone not knowing what they were doing and drilling holes in the wrong place. The car's electrical system was hacked up to convert it to 12 volt and it was a mess. I've fixed all that and went back to a 6 volt generator with a new harness. (Yes I'm a purest.)

Any suggestions or thoughts would be much appreciated.
