I want to change the 3.08 gears in my 78 K5 to 4.11 or 4.56 to compensate for 35-inchers. Due to the fact that this is a daily driver and I need to get to work, I plan to change the gears on the rear axle first and finish the front later, as time (read: money) allows. My question: May I damage anything in the NP203 if i just lock it in 4HI (H-loc position on the shifter) and drive around for a few days (weeks ?) with the front driveshaft removed? Thanks in advance!
