That's the hole I am using, and I am 1.75" away from rubber stop.
You are supposed to put the spacer on the other side of the pedal so your push rod is straighter.
Thanks for the picture I am going to work with it in that hole.
I asked Jeff at Keisler, but he wasn't sure and said that a tech would contact me with the info.
I haven't herd back from him yet.
