anybody have auto-6 pack car

:drinkers: I just bolted on six pack set up , gas pedal operates fine with full throttle but kickdown plate slot is too short, and I have adjusted it as far as it will go. all linkage is from 4 bbl car. Now the slot needs to be about 2-1/2" longer to operate properly IF I have installed everything correctly. I could drill a 3/8 hole some 2-1/2" further down and use air ginder to make the slot but it would take at least an hour. before I start ginding away can somebody take a measurement of the metal slider plate and give me dimension of slot behind the throttle arm in its resting postion, "I just want to measure twice and cut once" thanx
