I just bought a 79 3/4 ton pickup. It has a 14bolt rear and I think a dana44 front. 350 motor, and a 400 trans. I dont know which t-case is in it. There is a sticker on the drivers visor that explains shifting the t-case and says "full time t-case" at the top. Its has lock outs. Are those added by a owner? The shifter has HI-HILOC-N-LOW-LOWLOC on the handle.Which case is this? Is it a good case? It is stuck in hi gear. My second question iswhy whould the shifter be stuck?
