I assume you mean "dual wheel", not "duel axle", right? Your truck has been modified (and the weight carrying capacity seriously compromised) by somebody fitting aftermarket wheels to it. It would have probably been sold originally with 18" tube type tires on split rims with dual wheels on the rear axle, and somebody thought they were making it safer by using alloy wheels intended for a 3/4 ton truck. It's a good-looking truck, but don't expect those wheels and tires to carry anywhere near the weight the bed and suspension system was designed to haul. Jerry
The murder victim was drowned in a bathtub full of Rice Krispies and milk. The coroner blamed the crime on a cereal killer!

I have a dual rear wheel flatbed/stakebed (pto driven dump) and a single wheel that came with the 9 foot box. Both are 250 models which is actually GMC nomenclature for 1 ton. Chevy called theirs 3800. Engine in your truck would most likely be 228. Great looking truck - had it long?
