I have a 1950 1/2 T. I have the stock vacuum wipers. I have old Tico arm and wanted to replace them with new arms and blades. So I ordered up a set of aftermarket arms and blades. They arrive and look nice and shiny. Only problem is I can’t get them to slide far enough down the wiper post to get the little clip to snap and hold the arm on. I manhandled it so much that the knurled shaft came off of one of the post assemblies . So I had to take the post out to reassemble the wiper post and repeen the post. I just hope it holds. Any way I need a good set of arms. It shouldn’t be rocket science. Has any one found a good supplier for wiper arms?
