If I can get into 2Low, N, 2Hi, and 4Hi gears of my np203 T-case w/ the mile marker part time conversion kit, but cant get it into 4low, does this signify a linkage problem? It seems that the forward throw of the T-case shifter (for 4Lo) is limited by the "box" that the shifter is mounted to. Is this the problem, can the throw be adjusted to allow the shifter to mve farther forward for 4Lo? Thanks in advance for your help, you guys have already saved me hundreds of $$$'s!
