I've got an 84 k10 truck and the the pinion bearings are crapping out in the rear 10 bolt. i just bought a 14 bolt and i'm gonna get it over easter, in the meantime i've been thinking about "installing" a lincoln locker in my old axle if you know what i mean. i just don't know how well i'm gonna be able to drive on the street. i remember driving my cousins old derby car with welded spiders and it chirped like a bitch. should i break out the welder now or wait until i'm closer to puttin in the 14 bolt? all i know is that old derby car tore it up in the mud!
