its kinda hard to explain but Ill try, on the inside of the tailgate at the very bottom there is a hump, rolled out area about 3/4 " wide this roll runs all the way across the bottom and extends up both sides all the way up almost to the top of the gate with no breaks in this hump, 68s are different and 69-72 are also different in that hump. I am sure someone else can explain it better than I.
