yes that would be it! told ya dumb question. most of mine is fine except where the wind shiled was mounted at the bottom. The glass is still in the car but its missing a lot of that metal where the bottom of the glass touches it. I guess the silicone didnt hold up and it rusted out. Whats odd is the rest of its fine, the front where the wiper motor mounts, and the inside where the wiper arms are is fine too..
guess ill ad that to the list of parts lol...
Thanks!
