I went and looked at a '77 K30 single rear wheel truck last night and have a couple of quick questions. First, the Dana 60 does not have locking hubs rather it just has what appears to be full-time hubs (looks about the same as the old full-time Dana 44's). Can you just swap in locking hubs without any other problems? Gear ratio - I couldn't verify gear ratio but it should be 4.10, possibly 4.56, right? From what I have heard, 1-tons had at least 4.10's. Tranny and t-case - it's a four speed truck, assuming it's a SM465. My friend who looked at the truck, and is fairly knowledgible, said it was a 205 transfer case. I didn't get a good look under it because it was getting dark and was sitting in the weeds. Is there any chance it's a rare 465/203 combo since it has full-time hubs and the transfer case shifter looks the same as other 203 equipped trucks I have seen??? Any help would be appreciated.
