Need a E-Brake

Hi All,
I bought a 4speed car with a Ford disk rear.... all of the factory e-brake system was removed...even the handel inside (1972 Duster) I bought a used line lock for the front brakes...but worry that if the battery dies from what ever draw it takes from the battery...I am in trouble of rolling off down the hill.
So if anyone can give some advice or has the parts I would need to put the hand brake back in service.....please let me know. I would change the rear back to the 8 3/4 if it weren't for the price they are asking these days.
Again if someone has a rear in the 350 to 323 range drum to drum and lives anywhere near North Ga. 30512 Please contact me at [email protected] Thanks ! Bud :sad1:
