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

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?
Thanks, I believe you are right. It has 250 models on the side. I haven't driven it much but I had a guy figure out why it wasn't running well. it was a lead on the exhaust sucking air back in and causing a hesitation. He did some upgrades for me like converting it to 12 volts and putting power steering on it. I had to take the split rims off because if I got a flat tire, nobody in Atlanta works on them anymore. So I got some used rims off Craigslist and put the same size tires all around. I didn't realize the front tires were much skinnier and when I put the wide tires on the front, I could barely turn the steering wheel, that's why I needed power steering...lol. The problem with the power steering was the pullies on the engine and the pullies on the newer power steering were different sizes and the fanbelt squealed like a freight train!!!. Couldn't find anyone smart enough to fix it.
One body shop has it for years in north Ga. and started selling parts off it and replacing them with worn-out parts. Was very unhappy. So didn't drive it much. Had a divorce so she got the house and I got the truck...we were even...lol. Recently I found FINALLY a guy that could really work on the truck. He has had it now and is doing wonders on it. He has repainted it so the bed and body are the same color...he fabricated 4 pulleys so they are all the same size (no more squealing), added a mirror on the right side, replaced the front windows (the gas tank got a leak and in the summer the fumes broke the seals. cut out bad rust and fabricated new curved metal behind the fenders, fix the door handles, replace the window cranks, new rubber on all the windows, and built a hide-a-way mini step up in the back to make it easy to climb up in the stake body bed.
The only challenge he is having is replacing the rear window. The opening is 31 3/4 and all the windows made are 31". The rubber is only 1" wide so it is leaving a gap and haven't found a solution yet. If there was a 1/5" rubber it would work. It the window would come in 31.5" that would work...ugg I am putting in a rear window with a sliding piece to let air through but no solutions yet. If anyone has any suggestions please let me know. Should have it out of the shop in a few weeks so very excited to be able to drive it again. it has 43,000 original miles on it and I am the 2nd owner...
Looking forward to tooling around in it soon. Will post pictures when it is don.
That rear window is flat glass. Any automotive glass shop worthy of the name can cut a window to fit the opening in the cab, although I can't imagine why you'd have a window opening that's different from thousands of other Chevy and GMC trucks with the same cab. Are you sure you've got the right gasket? Jerry
