I was just in the market to get one. They are a little more of a hassle than a 9" (which I went with a custom made one, will get it this week). First off you will need to shorten your stock driveshaft by 1.6" or buy a new custom one. 2nd, you will have to send in your brake mounting plates and exciter rings to strange to be put on your new axles or spend another $300 to buy them from them. 3rd, Strange has a 5-6 week backorder on them. I priced what I wanted through strange, and with the 35 spline detroit locker, drain plug, backing plates, exciter rings and 4.30 gears the price was more like $3100 + shipping and that didn't count the driveshaft delima + the back order.
I ended up buying a brand new custom 9" set up unit for $2450 Shipped. Moser case, Moser 35 spline axles, Strange nodular third member case with Motive performance 4.30 gears and detroit locker. exciter rings installed and set up for 4 channel. Drain and fill plug. Timken bearings. can't beat that!!
