Yes, you need to weld it from the rearend axle tube over to the frame rail. The mounting points that will be welded to the axle housing and frame rail need to be straight across from each other, side to side. Now, the bar only need to be on a level plane when it is at ride height. Set your truck up on jack stands with a jack under the rear end. Center the rear end between the frame rails (take good measurments here it has to be dead on, dead on at ride height also.) Now decide on your mounting points on the rear end tube and frame rail using a level across the the pan hard bar. Mark these points with a Sharpie marker. A good frame rail mounting point would be the center of the rear most lower leg of your C notch (unless you have boxed in the entire frame). When you have decided on a your mounting points, Make sure to move the rear end up and down it's full travel to check for any binding or interference. Make sure you do good welding here. Clean away any paint or grime and wipe clean with solvent. These welds you are getting ready to lay down could be the differnce beween a solid rear end mount and your rear end in a ditch or worse. Good luck!
