Glenn, I believe you are correct. I think someone swapped hoods at one point and that is what throws it off. A C60 surely wouldn't have that 5/10 bolt pattern. I would have though it would have had daytons. I bet you're correct it probably had a 348 or inline 6. I find it odd it has Parts written on the firewall. I can only assume someone bought the truck out of a junk yard then put the 402 in it.
The story is this farmer's brother was kicked off a farm in the 80's that he was running. He had to get all of his equipment out of there so these were some of the trinkets he stored here. His brother used them helping out on this man's farm and then just left them. Luckily the guy has the title for the Dodge.
Another cool factoid about the Dodge is that this truck has the wrap around back glass which is ultra rare in one of these. I did some digging and these cabs were actually for 55-60 dodge pick ups. Seth, have any good windshields? :LOL:
Here are a couple of better pics of the front suspension.
