if its anything like my 71 duster there are two bolt welded to the baseplate of the gaspedal
you line it up with the firewall from the inside and then tighten the nuts in the enginebay
Those year darts with slant 6's had the pedal as diymirage has stated above ^^^^^
There are two studs mounted to the accelerator assy and the nuts go on as he described.
You can find used ones in good condition.
These years should be cable operated throttle. Make sure when you get the pedal assembly that you also get the little round plastic black "button" that fits in the larger part of the hole in the lever on the pedal assembly that the end of the throttle cable attaches to the lever. This button covers the larger hole so the cable doesn't come back out while you/her are driving it....
They are very small and easy to loose. Sometimes they get crushed when removing and installing if you are not careful... Make sure that you request the button come with the pedal assy when you find one...
Post in the parts wanted forum for one and see what you can get.
