I need to change axle ratios and currently have a 12bolt rear. I have a 14bff at the house ready to go but it has a govlock. If cost difference was not an issue, would you regear the 12bolt and add a selectable locker, or use the 14bff with the govlock. It's for a 78 k5, 350,350,203, 4" lift, 35" to 36" tires, light to moderate offroading. Thinking about weight, ground clearance, strength/reliability, and street manners.
