Re: 1976 K20 - Factory front Posi?
I don't know what years did what, but at some point an automatic with locking hubs became an option along side of the full-time option. These would have NP205s. It seems all '76s were full-time, but could be wrong. I know in '79 they could be had part-time auto for sure. Then on posi front, I don't know about in '76 but I know i the 69-72 era it was offered. I wonder if this guy is getting posi and full-time mixed up. The term "Loc" is used for shifting the NP203
