[1969 GMC]

I know that when I first joined this messge board, I wanted to know what t-case I had. It sounded to me like GM used divorced Rockwells early in production (67-68) and then married NP205 (70-72) but 1969, the year my GMC was made, you could have gotten a few. Married NP205, divorced Rockwell, and married Rockwell (what I have). So unless someone's done a t-case swap, I'd venture a stab at it being a divorced Rockwell.
