2.73 gear change

i have a 86 c10 with a cad 425, th400 and 2.73 gears in a 10 bolt with the g80. i was wondering on if i should change the gears or the whole rear. ik it would take a hit to my highway rpm but this is a back roads kinda truck. do the 10 and 12/14 bolts have the same u joints and what is needed to change the ring/pinion? iv replaced centers in fords b4 and built motors. just never had to mess with the pinion. i would like to keep sum kinda locker bc the snow gets deep round here.
