I used one that was from an 89 S-10, if my memory is correct. It was set up for an auto tranny, which I didn't use. It also had a tilt wheel. I had to do some modifying of the dash hanger to get it to set as high as possible in the stock 40 dash notch. I also had to tweak the brake pedal a bit to get clearance for what I remember as being the headlight dimmer switch that was mounted on the column in about the 10:30 position (under the dash).
I combined the lower steering shaft from two GM vehicles to get a long enough shaft to couple the S-10 column with the manual saginaw steering the PO had installed on the 40. By combining the shafts I was able to keep the stock GM slip joint on the double D shaft.
I was able to get most of the multi-function stalk to work. The only thing I had problems with was the wipers. I got the wiper on/off to work, but had to resort to a toggle switch on the dash for wiper high/low speed.
