truck leans to left

I noticed this from the back when its still on flat ground. I never noticed it from the front until yesterday, but it leans the same on the whole side. The guy I bought it from said he wanted the thing to "look" like a 4x4 and had new leaf springs put on the back. It was then too high in the back, so he had the torsion bars raised to meet it. I guess its odd to not have noticed this before, and I'm going out to measure the distance from the ground to the highest point in the wheel well right now to see what that says. I wonder if the torsion bars are out of whack and causing this lean? and whether it can be adjusted of course to make it right.
