Parking brakes with 8.8 inch ford rear and disk brakes.

So my rolling chassis 1972 duster has a ford 8.8 inch in it and I have a few questions I was hoping others who have been there done that could help with. So first off the previous owner had a 727 in the car and no park brake was attached. In fact the only this remaining of the park brake system is the front cable the pull handle mechanism and mid cables are all gone. Does anyone know a source for the brake mechanism a nicely restored one sold on here the other day but I'm not seeing any on any other site.. The car has Hotchkiss front to back chasis ties in place and I see the cable hole that has been welded over. I know I can line drill through the flange on the tie bar and route a cable through that. Next I read the post on here where one member had fabricate a good transition fro. The stock mopar cables to the ford rear end cables just need to try to contact them. I also have to go to the local pick and part and find the ford cables as they are not there either. Lots of work to figure thus one out as I am definately installing a manual transmission and need a park brake. I had thought about one of the local tunnel mount had brakes but would like to try and stay factory.
