Old thread I know.
John. You posted in another thread that both Trico and Anco supplied parts.
Is it possible that my original arms (the part that actually pushes on the wiper transmission) were Trico, and the original blade holders were Anco?
My Anco blade holders have the little red buttons to depress for removal of the insert, so they predate the more universal style.
I bought my '69 in '73 - it had Anco 815 15" Red Dots (anti wind lifts) on it, same as it had in '71 when I first saw the car. When I bought my Pace Car in '94, it had the same Red Dots on it. Both had Trico arms, Anco 815's. I have only seen them on the high option cars - SS's, Z's - I wondered for years if they were dealer installed or actually optional from GM. I consulted a very well known Chevrolet specialist several years ago - he told me they were an original supplier like Trico, but for one reason or another, the blades only came on the high performance vehicles. BTW, I ran across the Anco refills several years ago, NOS, and they fit the 15" standard Trico blades perfectly.
Somebody have another take on this ? I have always like the Red Dots in appearance over the standard Trico blades, will keep them on the cars regardless -
