I tried very hard to do the exact same thing. Looked everywhere. I even bought a universal short/adjustable wiper arm and one of those little adaptor kits that failed miserably. I finally just said to heck with it and ordered one of the ridiculously expensive ones from one of the catalog places. I would be very interested to see if you find a cheaper/modern alternative. Off the top of my head, the only guys that I know who have been successful with this are the ones who changed out the entire wiper mechanism with a modern electric-style one. I hope somebody comes along and proves me wrong here. In the meantime, good luck. Let us know what you find.
