Welcome, I have a 47 3600 that I just started on. I'm going to build a new gas tank as they are not reproduced by anyone that I could find. It is not the same as the 3100 under bed tank. My neighbor has a complete metal working fab shop with all the machines to do sheet metal. My truck is very solid considering it's age. Door are solid, cab corners are solid, box is repairable (wood ) but I'll replace the back fenders. It will be a lot of work, but, I enjoy this type of challenge.
