OK looks like Jeep Grand Cherokee 92-98 box is the way to go with no reduction in turning circle Just needs metric adapters for the hoses and suitable Rag joint to make it all work. This is the link to read all about it at http://classicoldsmobile.com/forums...-handling/19674-steering-box-replacement.html I am wondering wether this box will work in a heavier car like the Riv???
I can tell you now to skip the boxes from the later b-bodies (91-96). Unless of course you like being able to turn the wheel 2" in either direction before the car knows that you're interested in turning. Alot of the b-body guys are going with steering shafts from Jeeps and then switching to a Lee rebuilt box or converting to the 500/600 or whatever it's called box. That's the same basic box used in the early 2000's fullsize trucks like the Tahoe.
You don't need a metric adapter per se....the inserts that Lee Manufacturing sells drive down into the ports and convert them to inverted flare. Your original SAE hose threads are close enough to the metric port threads that they will tighten down and the flare does the sealing. Mine is set up like that and works great. Also, here's another exchange with Jim Shea....

I thought maybe one of those boxes with the truck coupler and Lee Manufacturing inserts might go in and work like I've done with my Camaro. I looked up a '93 Roadmaster and it weighs about 4200, pretty much what a '68 Riv weighs. Thanks. Steiner Steiner, Your reasoning sounds OK to me. It was the car division's call as to what size gear and the ratios, valve efforts, etc. The big bore gears were more expensive than the 700 gears. So putting a big bore gear on a certain car model was not taken lightly. Jim
