Here are some shots of a factory original from January '65-Dearborn. They have the "Trico Made in USA" on each end of the blade as well as the other writing where it attaches to the arm "3056160 Can. 63" Maybe a Canadian number of some sort...
Gary, you may want to do a little research on the correct style wipers.
I have collected quite a few wipers over the years and have them
marked with the VIN of the car they came off of. In going through
them the bright shiny ones that just have "TRICO" stamped on
them as shown in "rodster"s picture all came off of 65's.
Have a few off of 66's that look the same but have a dull finish.
Have a pair off a 68 that are a dull finish but are shaped a little
different, not as flat as the 66 style and have "Trico made in usa" stamp.
Maybe one of the head judges will chime in with their thoughts on this.
