Craig , the floorpan changed , so you'd have to do something about the front mount .
I will look at Daves 74 and see if the bracket that was made for it is still in it .
I do have the cup piece with the rod the rear clips in that goes in the floor off the 83 that got cut up if you want it . You'd have to put a small hole in the rear floor and sit this in it and screw it down .
