wanted full float rear axle with disc brakes

[bp71k5]

Pretty simple, looking for a full float (or possible semi-float) GM 8-lug SRW axle that has already been setup with disc brakes. Also need gears to be 4.10 and available for pickup in CA anywhere between Sacramento and Hollister. The closer to San Jose the better.

Update: Would consider 4.56 gears as well.
