65 short bed 3/4 ton?

[dozerbill72]

I found a 65 3/4 ton 4x4 with a 327 and a 4 speed that is a short wide box. Did the factory ever make this combination? The owner swears up and down that it is all original. It's in a poorly lit building and I had no flashlight the other day when I found it. If the axles have been changed how ever did it used factory u-bolts and plates for the larger rear end. I could not see any place where the frame had been cut and shortened. I also could not open the door to see the VIN because of another car beside it. I would like a little input before I go to the trouble of unearthing it.
Thanks,,,Bill
