1965 Dart unknown hole.

Here is the V8 (and slant with factory AC) gas pedal bracket. The hole in question is behind the large space besides the bottom two holes roughly as I marked
Exactly. That throttle cable-mount plate looked Rube Goldbergish when I restored it in 1965 Dart w/ 273. Then I got a 1964 Valiant w/ slant six and saw how it began with the rotating rod throttle mount, so the cable plate was a retro-fit to that. Stumpy's car might have a later-year cable throttle fitted to it. I saw an early A in the junkyard like that, obviously a kludged-in setup, probably to retrofit a 318 engine.
