I would never scrap a 39 Mercury frame if it was solid. It fits all models Merc 39-40. There has to be someone that would give you scrap price for the frame and put it to good use. I think it wil fit 39 thru-48 Merc and 41 thru 48 Ford, 117 inch wheelbase. If I am wrong someone will correct me.
maybe i will just hold onto the complete frame then....thanks for the help...i wasn't sure if the four door frames were different from the two doors
