The rack must be mounted to the front axle to prevent bump steer which means a slip joint is required in the steering shaft--not desirable. There is a unit called "Uni-Steer" that just uses one rod out of the frame mounted rack in a cross steer fashion like 48 and older Fords had. Cuts down on bump deflection but still not perfect. Many have used the early to mid 80's Toyota pickup p/s boxes mounted in place of the factory box with good results but the popularity has pushed the price up. Before you go exotic I'd get everything brought up to like new specs and drive as is (probably runs about a grand). If you like the old time way it rides, handles, drives, the air noise, and the sounds and smells of an old truck then your good to correct what short comings you feel it needs rather than spend a bundle and then decide it's not for you.
