I am now offering a posi unit rebuild service for 50 dollars. Please send us your 8.5 GM Posi Unit and we will install the new clutch disc and shim kit. If the winning bidder decides to use this service, round trip shipping is the buyer's responsibility. I will send you a prepaid UPS Label that you just have to tape to the box. Drop the box off at any UPS location or simply give the box to the UPS driver. If there are any other broken parts in the unit (Side Gears, Spider Gears, Cross Shaft, etc.), the buyer is responsible for the cost of the new parts. The labor rate will remain the same. I can also install new carrier bearings for the cost of the bearings or send the bearings with your posi unit and I will install the bearings at no charge. Please contact me for all details.
