Rack and pinion

[Derek69SS]

I wouldn't recommend it. There's not really anything to be gained, and there's a whole lot of geometry that can be messed up if not done exactly right.

A good quick-ratio steering box and rebuilt linkages will feel and perform just as well as any R&P.

I'd recommend doing the Jeep Grand Cherokee steering box swap for a good low-cost upgrade with excellent performance. I'd put it at about 90% as good of upgrade as one of those $1800 rack kits, and can be done for about $80-100.
