Borgeson box and steering coupler from Bergman. You're not going to get any better than that utilitzing factory style parts. It eliminates the slop at 12 o' clock, tightens the steering up and adds more ratio. I bought two of their boxes and have been very pleased with the results. Feels like rack and pinion. If you go the route do yourself a favor and order a pump to go along with it as well since it has the correct valving to match the box. You can get everything through Bergman Autocraft.
