GMC history

[factorystock]

IMO, one of the most interesting models in GMC history was on the lighter - medium end. The 3000 series ( '60-'62 GMC or Chevy C 40) was heavier than a 1 ton but lighter than a 1 1/2 ton, making it a 1 1/4 ton. They had the same 5-10 lug system used in 1 1/2 tons. It disappeared between '63-'67. It reappeared between '68-72 as HD 3500 or HD C 30. In '73, disappeared again for good. GM gave up on this weight class, today it is dominated by Ford and Dodge. Hard to beat the curves of the 60's.

Yes, somewhere I have a '62 GMC Stake/Flatbed brochure and those models are listed. The 1991-2002 3500HD cab and chassis models were similar, and also used 5 front/10 stud rear hubs but with 19.5" tubeless wheels.
