Well heres the low down. The truck is a 78k10 with that 203 t-case. The cab is from a 2wd pickup so there were no holes for the floor shifter. Today I cut out a hole and istalled the shifter that i bought from clarkjw24 (thanks again!). I connected the linkages which I compared to my brothers 79k5. (before you say it, that nut holding the linkage in is temporary) Now the problem is the t-case will only fully engage "Hi Loc" and "Lo Loc". If i go in to "Hi" or "Lo" at any time, then the t-case seems to slide into "N" the minute that I slow down. What could cause this and how bad is it to drive on the street in "Hi Loc"?
