Ok, does the Smith Racecraft pedal made for 1st gen Nova come apart some kinda way I cannot tell, appears all one unit. Does it install from engine side? Which side does the odd sideways mount plate end up on? Where does the little brass looking catch go, in the interior side and it bolts up? Having problems figuring out, went to Smith cite and they show camaro type install, 1st gen Chevy II different. Thank you, Brett.
