'75-76 Parking Brake pedal?

I have the same issue. from what i understand or have been told the kick panel on the 76 duster was different with provisions in the metal for the foot operated brake.
I am looking at using a handbrake from a Holden HQ and mounting it on the floor between the seat and the door ( it drops back down again so you don't impale yourself getting out of the car) just trying to work out how to get the cable to work
