The steering slop, i've seen it a number of 2nd gen's, is the sector shaft on the steering box. I had a friend move the wheel back and forth, the sector shaft moved side to side. You can get a new replacement gearbox and you'll have the same problem. I've had the stabilizer for over a year and it keeps the front end tight.
As far as the "Rock Solid" Ram Truck Steering bushing, you'll have to put more effort in turning the wheel when its cold. The "tie" the guy supplies is useless. This worries me as well, you'll be able to pull the steering up. I also see a design flaw and this is why Chrysler put a spring at the end. The FSM doesn't go in depth with the steering column but I found out when I rebuilt my column. Theres 2 ball bearings, one on the top and bottom. Theres a wedge that keeps the shaft from having play inside the bearing bore, top and bottom. That spring keeps the load on the top and bottom bearing wedges and keeps the shaft fixed.
If you steering column "vibrates" over rough roads or bumps, then your intermediate shaft is frozen. If you can't move the intermediate shaft up or down. You'll need to take it out, remove the dust boot and soak it with PB Blaster. Use a hammer to work it in and out (don't hit the u-joints). Eventually it'll break loose. Once thats done, grease it and zip tie the dust boot.
