I'm looking a a 76 k-10 to buy. Everything I've read says that this truck with an automatic trans. will have the np-203 case. I'm almost positive that it has the 205 case and the owner claims that it's original. Was there any deviation from the 203 case? Was it an option?

I don't know about stock options but there should be id on the back of the case on a tag that will say np-203. You also don't say if it is a six or an eight. I believe the six came through with the 205 case.
hope this helps

I know this isn't a sure thing, but does it have manual hubs? If not it is probably a 203 for sure. (probably for sure, how great is that).

Thanks for answering my question. The truck does have a sb350 and lockout hubs, but I don't know if either are original. I have no reason to think they aren't, but the truck is being sold by a dealer and he doesn't know the history. I'm going to check the vin# and look for the I.D. tag on the t-case. The shifter has 4L-N-2H-4H on it and that's one clue that makes me think 205. Thanks again for your help.
