My newly aquired truck, a 1966 chev. 3/4 ton fleetside has about 4 inches of freeplay in the steering column. I know sometimes you can go to the steering box and make some adjustments to hopefully get rid of some of the freeplay. Can anyone walk me through this so I can give it a try. I realize the front end may need a rebuild, but it looks as if the steering box has never been adjusted.
