2000 SS SLP package rearend

[87lt1rx7]

I just bought an LS1/T56 from a guy and with everything else threw in the rear end from his wife's wrecked SS car. It came with bilstein shocks as well and so, from research, conluded that it may have been an SLP package car. If so, the rear end is an "SLP ultra torque". Has anyone heard of this? It is supposed to have an auburn limited slip and 3:42 gears if this is true. What do you think one of these would sell for?

The rearend will sell for $300-400.. It should have the Aluminum rear end cover with fins on it as well..
