2 piece driveshaft

Hey guys, I hope someone can help me out. I've got an 85 crewcab that I've build a whole new frame from scratch. My problem is I'm using a 2 piece driveshaft, but I'm trying to get my steady bearing x-member set up. I have 4 deg down on my output shaft, and 4 deg up at my rear axle. My question is, where should my steady be in relation to my output shaft, i.e. 4 deg down, 0 deg(level)? I can't seem to find a straight answer from anyone. Someone please help me out so I can get my body on.

You'll want it off set a little to avoid vibration. And if your tranny is lined up with the rear diff then you'll also want to off set the carrier to one side a few degrees. You never want 2 universals on opposite ends of the shaft perfectly lined up. It will cause vibration and wear.

gm drive shafts are uasually offset slightly to one side so the needle bearings will not wear out.

Look at this link it should help. JIMMY
