Longhorn trucks - what were the options

[C10_crazy]

I recently read that the Longhorn trucks were available in either 3/4 ton or 1 ton versions. What are the differences between the two options from a chassis and suspension perspective? Are they both 8 lug? What is the differences between the 3/4 ton and 1 ton rear suspensions and differentials?

I'm curious because I recently bought a 1967 C30 dually truck so that made me curious about what variations were available. The Longhorns weren't built as a dually (as far as I know anyway). I've seen some Longhorns and I'm just wanting to learn as much as I can about what Chevrolet offered from 1967 to 1972 (I don't think the Longhorns were available until 1968).

Thanks for your help.
