So I got the new water pump gasket in my '37 and it quit leaking so that's all good. A bit of trivia. I am re-upholstering the seats and found a paper tag attached to one of the springs. It says " Fort Pitt Bedding Co" and has a list of patent dates starting in 1925 and going through at least 1937. After that it gets hard to read. I wonder if they made the springs, did the upholstery or both? Use that to stump your friends who think they know everything about these trucks.
