Have the 3.73 12 bolt out of my 77 k5 i want gone. Welded rear. The 4" lift parts are the ubolts and nuts ( one u-bolt is a bit bent at the top but it doesnt affect the nuts ) and the steering arm. This is for the factory drivers side steering not crossover. All the steering stuff for $20 and the axle can be had for $50. Thanks!
