I will assume that you have manual steering now. I think you might be able to cut down your manual steering shaft to use with power steering. The shaft is 2-piece & telescopes like an antennae. You'd probably do most (if not all) of the cutting on the center/solid piece, set the total length & then cross-drill/tap some holes for hardware store nylon bolts....trim off the excess & you have new plastic shear pins.Looking for the shaft that runs through the steering column for a 1970 B Body with power steering. Located in northern NJ.
