Took it to a local shop to get installed, was not impressed with their knowledge when I asked them questions about the final install. a friend took it to a shop about 1.5hrs away from me who has installed another members gears and they said they are way off, backlash wrong, preload on the bearings wrong, crush collar not fully compressed ect. They noticed a spacer on the ring gear. I spoke with specialtyz's guy and left a message with mark leader I think I got everything figured out, they shimmed it wrong and to make up for improper shimming used a ring gear spacer. the shop said they will take care of it and have it by tuesday hopefully, so I have my fingers crossed.
