Rack and Pinion

Well I just got an 88 5.0 mustang gt and the people before me ghetto rigged it BAD. And the guy was stupid and though that if he ran a shorter belt and bypassed the power sterring pump he would get more power to the wheels, well in theory it works but now I think the rack is fryed, the steering is real stiff and the pump is attached with the belt running to it and full of fluid. And this car has been sitting for 2 years before it got to me. Any ideas or places I can get a cheap stock rack would be apperciated.
