You might as well swap the uppers back to the correct sides. Its way too much. The upper limit is 9° and thats with a suspension designed for it. I'm still skeptical of 7° for a stock suspended C10. Rob McGregor addressed bumpsteer (as well as roll center among other things) in his "Make it Handle" thread. The steering arms would have to be modified to drop back down (heated and bent) or the tie rod would have to be flipped underneath the steering arm to correct Bumpsteer. A good alignment is something you can do to any truck but its only when you modify the suspension that things get hairy.
