Here's another chop, cut, rebuild. A Mantua F7 body on a Proto 2000 FA1 chassis. It was a shotgun wedding. The truck and weight supports inside the body had to be cut out. On the P2K chassis the front coupler pocket had to be removed and the headlight fixture had the be removed. The corners on the front of the frame had to be ground off (1/8" each side) to allow the body to fit. Naturally it runs like a dream. Here's a photo of it in it's final form, if you can get over the Alco trucks that is.
