That sounds like the part of the column that the 69's use for the neutral safety switch/ignition lock out. As I dont know about the 68's and if they had that or not I cant really tell you, but I thought that they didnt have that on a 68 as the safety switch was located in the console. Do you have a auto console shifter? Take a look at this and see if you can tell me what item it is. http://thefirstgensite.com/library/partscounter/illustrated/front/strcol1.html Do you know for a fact you have a 68 column and someone in the past hasnt swapped it out?
