Mike ,
chev1 has the answer ... I think you'll find the 67-72 C10 tilt will work , but it'll put the neutral safety switch RIGHT ON the firewall/floorboard exit. Difficult to hook up , not impossible , but a pita. The van column is shorter and a definite advantage. The adaptor kit is available at most local parts stores for about #10.00 or less ... Unless ya GOTTA HAVE chrome/polished , if you need a steering knuckle or two , they're available at tractor supply stores for about half the cost of - (pick a high buck brand).
P.S. : chev1 knows a little about AD trucks
