I had that same gas pedal in my 67 Chevelle 327 4 speed and same T handle and that was my first stereo system I put in my Duster. Brought back some memories.
The Chevelle had the tube shifter with the T lock-out. I got into a run with a GTO and had him beautiful out of the hole and went for second and bent the shifter all to hell. Needless to say I lost. But I put a Hurst Competition Plus with a T handle in it. I never bent that one LOL
