Touche'! I'm not above fabricobbling something like that, but if somebody else is willing to do the fab work and sell me one, I don't mind forking over a few greenbacks. The tapered hole isn't difficult to manage- - -there are taper reamers available with the correct angle to turn a drilled hole into one that fits a tie rod end. The project I'm contemplating involves mounting the steering box on top of the frame, with a straight Pitman arm pointing downward and running an adjustable length drag link a couple of inches away from the frame and parallel to it. That should allow the steering shaft to run along the top of the frame rail, out of the way of exhaust plumbing, etc. A universal joint or two will connect that shaft to a shortened original steering column, or an aftermarket item. Only one problem- - - -the steering box will work backwards when mounted that way, so I'm fabricating a simple, rugged spur gear box to reverse the steering shaft direction just ahead of the power steering gear.
