Is it for the e-body in your sig pic? I'm mocking up one in a 67 b-body right now. I'm going to use a Lokar kickdown cable for the 727, but installed into the original throttle cable hole, attaching it to the original pedal fulcrum bracket. The electronic pedal will push on the original bracket, which will "pull" the cable.
I just got the cable in the mail today.
