I just posted a new ad on Airstream Classifieds.
I have both original windshield wiper arms (and blades) from my 1982 Airstream motorhome. Trico is the brand. These arms look rough and need to be painted along with the fluid assembly shoud probably be replaced as well. These arms do not come with the serrated nut thingy that fits inside of it that attaches to the bolt that comes out of your motorhome. If you have this "nut insert" and just need a replacement arm then these are for you.
I will sell each for $7.50 plus shipping or both for $10 plus shipping.
You can contact us by filling in the form on the right hand column of the ad listing:
