As I understand it, Silverados are the high end models of the 80's K5's and Cheyennes are the high end models of the 70's K5's and I think that CST's are only for the 69-72's but I'm not sure if that last one is right.... /forums/images/graemlins/whistling.gif
[/ QUOTE ]Wrong, Silverados have been the highest models since like 73' or something. Cheyenne being the second nicest backage, custom deluxe, and scottsdale being the bare package if I remember right. This order stayed the same form 73' to 86' or 87'.
