Ummm...?
Disconnect your brake lines and suspension, remove the rear axle, and bring whole axle to shop.

I've only installed a couple of lockers, but the guy that worked on them with me has done a set of gears and says that they have to be set up in the axle housing. He said it has to do with the dial indicator mounting points. He also said something about endplay? I believe he was saying that you do your final setup and checks with the axles installed, too.

Talk to the race shop, make sure they didn't mean for you to bring the axle down there.
