Another good idea Quindel54.. I have seen this done on other trucks at shows like you said ,,just take whole wiper assembly off and put on a pretty chrome nut,infact a friend of mine last I knew was looking for somethng to put over his wiper threads on his 51 Chevy Truck ,
Once we each drove our trucks to a show in Seaside Oregon some 50 miles from our homes in Oregon where I used to live and of course on the way back it rained,, I had wipers he had some sort of window rain clearing liquid and he said it didnt do the job very well ,,lot of wind too..so beings I live here in Idaho where the sun shines kinda as much as Arizona (just had to throw that in bartamos,:) I will maybe try some of that rain stuff out .. what a bunch of great guys you are ..sorta like swapping tales at a car show..
