'30 Windshield Wiper Hole Size & Location

[30 Tudor and Coupe]

I am working on a '30 Town Sedan that someone has welded up the wiper holes. I have a '30 Coupe and Tudor I could measure but would like to have the correct dimensions. I recall seeing them somewhere but can not locate them again. I have checked Marco's site and every other one with no success. Does someone have the locations and hole sizes for the vac wiper?

Thanks in advance
