Wiper arm and blade questions

[1966burb]

I have a set of new reproduction wiper arms and blades on my burb which are just junk-- right out of the box. Would be fine for show only but not for use in a rainstorm. I am sure I can find a set of nice original arms and polish them up but what about blades? I think TRICO RB 12 blades may be correct and they show up on Ebay all the time as NOS, but 2 things, they also fit early Corvettes and sell for Corvette prices. Also the rubber on them are usually pretty dried out. It does rain in WASHINGTON state once in a while, so I would like good wipers. Thanks, Jim
