But Its common knowledge that 8 lugs means C20 or C2500 there 3/4 ton trucks or up to 2 ton trucks.

One more easy way to tell if you have a 1/2 ton from a 3/4 ton from 1950--1970.You have to undo 8 small bolts to remove the rear Drum on a 3/4 ton 8 lug truck 1971-72 used Dana's where the drum slides off

Im not sure where you were going with this but its my understanding that since GM started using the C/K designations in 1960, Chev's were C10 (half Ton), C20 (3/4 Ton) & C30 (1 Ton) for 2wd and K10, K20 & K30 for 4wd's. GMC did not use the "C" designation, though their 4x4 versions had the "K" designation. GMC Model numbers for 1/2, 3/4, 1, and 1.5 ton were 1000, 1500, 2500, and 3000.
