727 parts needed for RB install in a 69 barracuda
or zip tie the kick down lever on the box halfway through it's travel (and adjust that to get the shift points where you prefer) and use the shift lever for the very odd occasion you'll need 'kickdown' on a big block 'a' body. that was what i did for my 65 dart with a 440/727, and i kept the column shift for the sleeper look inside too. i very very rarely had to down shift as there was enough power even at low revs to break the tyres loose so there wasn't much point.
