Is there a difference in steering boxes?
My dad is building an '89 IROC-Z that currently has a manual steering box on it, and he wants to put power steering on the car. He's got a '91 RS parts car that still has the steering box in it,but isn't sure if there is a difference in the Z28/IROC and lower model steering boxes. Would an IROC's steering box have a better ratio than the one on his RS?

Are those letters actually stamped into the box itself or is that a partial RPO code? If it's an RPO codes that won't help because the sheet is completely gone on the IROC that we're building, it has ZERO interior in it.
