Take the old axle out, put the new axle in and connect up a switched source of power to the elocker - or, sell the rear 44 and get a locker put in to your existing 44 - granted it does not have the same spline count as the rubi 44, but just about every bit as strong IMO. Pics of the swap! Make SURE that the rear and front axle have the SAME gear ratio!

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
