If your interested in the Ox Locker, I'd say talk to Matt, he's been doing a little homework with the R&P and there might be a solution that is easier than mine. All in all, I love my Locker, but the work to get it in is pretty tough, but the ox guys said they documented everything for the install, so they might be able to help you as well.

After saying that, ARB and E-locker are pretty easy installs from what I'm told.

You can PM me if you have any other questions.
