The wiper blades were worn out on Sharondipity, our 38' Sedan (Dick and Patty Morland's former "Patty Wagon"), and I looked in vain for replacement blades that were not black. The arms and blades were Anco, and Dick said they were on the boat when he bought it. The once ubiquitous yellow metal Anco cabinets from garages and gas stations were no where to be found at any local establishment, and a search of the internet yielded nothing. Finally, I found that Trico had released a 15" stainless steel blade (Part # 55-150) for vintage (read 1960's) cars. Advance Auto Parts had them (SKU# 5070457) for $7.88 each, so I had my local store order three (you can also order online - see link below). When they came in, the connectors wouldn't work with the old Anco arms. I had to use a 3" cutoff grinder to take the old ends off and shorten the stainless steel arms, but then regular and titanium tipped bits wouldn't drill the needed holes for the retaining "catch" on the new blades. I bought some cobalt drill bits (a set was on sale at Harbor Freight) and voilà - I think the results are excellent! I just thought I'd pass along this tip.
Nice! We need new blades as well.
Thanks for the great information.
The Superdisc also mentions some sources. I am not sure if the items are still available.
