Turn radius

[HomerJ]

A couple of years ago, I upgraded my front brakes to disc. At the same time, I replaced my factory power-assisted steering with a more modern power steering gearbox. The internal stops in the gearbox have increased the turn radius by a huge amount. Is there a factory gearbox that doesn't have the internal stops or that are more forgiving than what I'm currently using (from a 71, I was told)? A lot of folks on Chevelles.com put gearboxes from mid-90's Grand Cherokee's on their cars. Would this box bolt up to our trucks? Is it stout enough to stand up to the increased weight (if that even matters)?
