The kits' value comes in the fact that its comes with a machined
caliper bracket specifically crafted to fit your stock axle/spindle set-up, also
they also come with new mounting hardware & the rear spindle adapter for the stock truck; this allows use of the stock roller bearings; NOT the ball bearings you have now.
In my case the CPP kit came with late 70's Camaro rotors, calipers, etc. I thought it was worth the price, bolted in, and works great.
