I have a 1941 1 ton long bed that is my daily driver. It came out of North Dakota and was used to pull a hay baler. I purchased it completely stock but once I got it on the road and discovered that top speed was 45 mph with a very low rear end ratio I upgraded the complete drive train to a SB350 engine, 700R4 transmission and 3.73 rear end. Resulted in 70 mph at 2,000 rpm. Disk brakes on the front so I have a great hiway cruiser.
