The spare is a formula desert dog just like the others. The tag under the hood says Goodyear but when my father in law purchased it he ordered those specific tires for on it. He told me that he had to pick options out of a book to put on it. He also said that carpet was another thing he had added from the factory when he ordered it. I dug through the glove box and found the original sales slip from the dealer with his name on it and another paper that says it is the odometer registration. He is the only owner except me but I have not transferred the title to my name yet. I took pictures of the inside interior, under hood including tag, the spare tire, and the other documents that I have. He told me that he might have the catalog that he ordered from somewhere. I also found a picture I him with the truck after he bought it with a promotional t shirt given with the truck when he bought it new. I explained to him about the tire issue and he said that those are the original tires that he ordered with the truck and that there were never good years on it, he has no reason to lie. I also took pictures of the odometer reading. In one of the exterior pics of the truck I just took you can see where the window where it sat for 33 years faded the paint and the yellow stripe. He said he only drove it a while and let it set inside the garage because he didn't want it to get ruined with salt on roads and weather. He also told me that only two other machos were ever sold from that dealership in our area. One was a silver long bed and the other was a yellow shortbed. He said they rotted away. If you knew my father in law you would understand why it sat so long. He has a dart swinger with 3000 miles and matching numbers, he is a mopar fanatic you could say. If some one contacts my email I can send the pics to be posted, I haven't had time to figure out how to do it, thanks Chris .
