My '39 120 coupe came with no trace of the windshield wiper system. I have sourced a set of transmissions/towers. Two questions: what holds them to the body of the car? I see that there is a threaded boss on the back of the casting-is there a plate or bridge of some sort that a screw goes through to pull the transmission tightly to the body? Also are there gaskets for the transmissions? I thought was getting the parts list down but I'm stumped here. A quick look through a couple vendor catalogs didn't turn up any gaskets.
