Hi Marvin. I mounted mine so the rear u-joint of the brownie was at the same location as the carrier bearing. So that way the rear drive line length didn't have to be altered. I was lucky in that the u-joint of the carrier bearing and the back u-joint of the brownie were the same, so that was just a bolt up operation. The front drive shaft had to be shortened and a slip joint added too. I put the brownie at the same elevation as the carrier bearing, so the rear drive shaft is also at the same angle as stock. The front drive shaft is at a bit more of an angle now than stock because it's shorter, but I haven't had any trouble.
You'll love it once it's installed and good luck.
Paul.
