Hi, I'm kinda new to this site but have had my K5 for about a year. It's a 1983 Jimmy w/ a built 350, th350 w/ a transgo shift kit, an NP203, stock axles/3.08's and 31's. I also have a 4" lift in the garage. So my question is, what is the shift pattern for this T-case? I've heard something about a "hi-loc lo-loc" but don't know much else other than where low and high are. One last thing, will I have to modify my driveshaft(s) to install my 4" suspension lift (when it warms up)??? Thank you in advance DANO If you ain't stuck, you ain't tryin!!!!!
