For steering, I opted for a simple rack and pinion setup taken directly from Ford Mustang II applications. This is a very popular aftermarket item, inexpensive and plenty of available sources. I bought mine from Speedway Motors along with mounting bushings and hardware. The steering wheel is also from Speedway as is the steering column. I had to modify the column to shorten the length, the column came as a nice package with a round aluminum tube cover over the shaft. Both the shaft and tube were cut to length and then reassembled.
I cut a 2 x 2 x 1/8 inch 90 degree angle steel to length and cut notches in each end to fit over the frame tubing and also drilled holes to bolt on the rack and pinion. I welded this into the front suspension frame area and attached the rack and pinion for fit. I then attached the steering joint coupling to the rack and pinion and to the steering column. I will hang the column at the appropriate distance on the dashboard area once I get the dash built and fitted. Here are some pictures of the steering assembly
