Hi help needed I have brought a CMP what I believe to be a Artillery gun tractor please see photos any info would be good I think it was a beetle back originally but the back has been chopped off and a GMC back put on it has the winch and the engine not sure if it runs, I would like to restore it back to a gun tractor. The only ID is the chassis no which looks like J844N2685
Any info or plans for Fabricating the back please
Thanks
