General Maintenance & Repairs - Looking for a new intermediate steering shaft with no plastic or runner bushings!!!!

I have a 2002 Pontiac fire hawk that's turbocharged. The turbo is located on the drivers side of the engine down low on the block and melts the plastic in my steering shaft. Does any one know of a direct replacement for that intermediate shaft preferably with out plastic or rubber bushings or is it jus best to buy new knuckles and shafts and assemble one on me own.
