Confused? 1972 swb

[J-72]

New guy here. I need help trying to figure out exactly what i bought. (Don't know if i got screwed or what.) I bought 2 1972 trucks 1 Lwb and 1 Swb for $2500. I got both clear titles for them. The story on the trucks: the Lwb was running until the father's son installed a radio in it, (he wire it wrong) and it caught on fire. The inside cab area was toast but the rest was fine.---this makes the truck the official donor now. The Swb supposedly he bought from some guy and it was a Cheyenne super with no motor or trans. The man was going to do a restore project but he was hospitalized for cancer. So he sold it. So after getting the truck home i look more into it. I found that the vin plate, and frame number match along with the title. But the glove box vin does not match. Also, above the vin plate, there's a small red decal that says (reassigned vehicle identification number). So once again i don't know if its a Cheyenne, Super, Custom, Deluxe? Or if the truck was stolen? I will post pics up soon. The original color was medium olive poly--i found that behind the padding on firewall. Any help is appreciated!
