I did it the old fashioned way and got a rear bar at the local salvage yard from a '90 Bronco II. $20 for the bar (PITA to get out of the BII laying on my back with hand tools), and some elbow grease cleaning it up and getting re-painted. I also found new upgraded urethane bushings for it at the parts store for $9 and put those in. It definately handles better, but my truck is lowered also. The only bad thing about it is that I still have an open 3:55 rear end and if you try to power into a corner, the bar will unload the inside tire enough to cause it to spin. I plan on getting a limited slip/disc brake rear axle from and Explorer sometime anyway so that should help. The cool part is that the Ranger frame already has the empty mounting holes where the bar goes so it's easy to put it in. I have not upgraded my front bar and don't intend to although I would like to find some upgraded urethane bushings for the end-links but have had no luck finding any yet.
