Hello , I have be trying to figure my truck out also Ven # BG693640 . I was told it is a 45 1.5 ton flatbed has a 216 in it. owned it for 5 years put it in my barn. I am not sure what Iam into here, hopefully not over my head. about to start working on it. runs great, no body rust was in a building form 1973 till 2013. fighting the tire issue first. Wheels in good shape and lucky to have a shop 2 miles away that will work on the ringed wheels. Tries on it today are the 17.50-20 hard as rock. The tire shop says they might be able to smash a 18.25-20 on it thinking of ordering one for a test. also a bubby told me about a shop in Dallas that has wheels of all sizes with no centers and the will build center to your specs or cut out yours, working on that next week, would really like one fat tire no more dual.
