I know this has been covered over and over, but I'll give it a try. I got the 14 FF mocked up under the blazer. My floor isn't exactly level. I took my degree gauge and placed on the rear of the transfer case and got 5 degrees up or not level ( I have the transfer case dropped 1 inch). I've got the 14 FF placed on the level side of the rear. How many degrees up or down do I need on the pinion angle? I know this is a simple answer, but I am brain dead right now trying to get this rear in the blazer. Any help would be greatly appreciated. Thanks. Going to home to think about it. Work on it some more tomorrow.
