rfs56trk,the 84-87Toyota 4x4 steering box you are talking about,do you just remove original steering box,on the AD trucks,and put the Toyota,back in the same location. I have a 72Chevelle steering column linked in with my original steering box on a 51Chevy 3/4ton.I have 350 engine sitting there with hugger headers. Any info would be appreciated.I have the power steering kit that Achipmunk,has on his Suburban.I don't have it installed yet. Looking for a better way to install without having to remove the fender on the driver's side.Thanks
