Now in deep with Super Six conversion KICKDOWN woes

Spent all weekend doing the super six conversion. from my original 66 dart 225 Holley 1 bbl, to the Super Carter bbd, manifolds, gas pedal, linkages.
Ok so I was able to install everything except the kickdown linkage. I removed the orig kickdown, and the one I am trying to install has this bolt type pin connection. First I tried with bolt on right side, no way cant move, hits the body. Then tried with bolt on left side, I can get it on but it cant go back n forth all the way back, it is hitting against the body. There is really no room in there for this piece. What am I doing wrong? Is there another piece that I can fit instead? I am really at a loss here, I am supposed to be driving this car to work this week.

I am concerned that if I drive it as it is, even to the tranny repair shop, if that kickdown piece gets jammed I am in big trouble. I was even thinking maybe it gets installed from below, upside down, but that doesn't seem right to have the cotter pin keeping it from falling downward.
help please.... and I want to tell you all how much fun it is to work from under the car in this crap tiny space that is the transmission kickdown. At one point I almost decided to remove the damn exhaust pipe, but didn't.
