Thank you guys! Its so hard to tell what was originally offered due to all the swapping these trucks have seen throughout the years. Why wasn't the 400 offered? Seems like a good fit for a 3/4 ton 4x4. Also, why we're on the subject, was the engine lineup the same for these as C20's? Were there any non Dana 60 rear ends used that are less than desireable? I've found a 70 CST 350/th350 with the "round" cover rearend and Dana 44 front. What axle ratios were available? Many or just a couple around 4.10? Maybe a better question is what were the differences between a K10 and K20 regarding drive train options?

I need to see if it is a NP205 but if not, are there any to avoid?
