I am lusting after a '39 to '46 1/2 truck. Worked on a '51 today for a friend and the shop talk got around to the passenger compartment size on these years of trucks. My buddy says they are small inside and I would be a tight fit. Well Ok, I'm 6'1" and need a diet bad at a tad less than 300 big ones. It's the beer with all that shop talk. So am I to big to fit into my want-to-be-mine truck? Thanks
