LS diff install in MN, IA, WI?

[Bill Lattimer <m22@skypoint.com>]

I know I asked this before, but I thought I'd take one last pass on the list
before I finish building a crate for my diff.  Does anyone know of any shop
within 500 or so miles of Minneapolis, MN that would tackle installation of
a Quaife limited slip?

Thanks!
