Story is that GM stopped production of Hummer 2 and they were left with 100s of extra axles with E-Lockers installed and then they sold the axles to wholesalers.
I just picked one up, brand spanking new for $375US can't beat that (I made an offer and they accepted it)
Located in Burnaby, they still had a few left last time I checked.
They have some 10bolt E-Lockers too, look at sellers other items
