My original wiper arms and frames are in good condition, but I cannot find just a refill that has a 3/8" wide steel backbone. Trico makes a Classic Series blade that will attached to my arms, but the blade is the newer beam style.
What are you guys using?
My car is a convertible so, I wont be driving it in the rain on purpose anyway,
but you gotta have wipers!!!

 

This post might be a bit late, but:

I have 63 F-85. I ordered the Classics from Advance Auto Parts, simply took the blades out of the frames when they arrived and put them into my original Trico wiper arms. Worked fine.
