thanks for the replies. i measured everything and found what i hope i will need at honest charlie's speed shop. i called them today (helluva decent guy on the phone) and ordered all the weird stuff and hope it will work.
6 to 8 inch adjustable wiper arms
9 inch wiper blades
2 universal motors with built in switches.
considering what i've been thru, i might take some pictures and post them here. i've seen guys with studebaker trucks, as well as a very few internationals that have fixed them up, so maybe a resource for us with "oddball" equipment might could use the info.
wife and i went to D.C. last year for vacation, and are thinking about niagara falls in a couple of weeks. this time i want to go with working wipers and a new seal around the crank out winshield (a blessing with no a/c).
