Every so often I can get it right with my 69. I think if I catch the top of the brake pedal with the ball of my foot, and the gas above the pedal its self,with my heel, or ankle or something,
I can get it to work. Otherwise I end up lurching with too much brake and not enough throttle. So, my solution is get on the brakes, get off, double clutch the shift, then back on the brakes. Not exactly fast, but its easier on the transmission. It bugs the heck out of me as with the track car, each heel and toe near perfect, no thinking about it, just perfectly smooth.
