Someone removed the entire parking brake- Im trying to get it back on. I need the Parking BRAKE ARMS for both rear drums- its the arm that the parking brake cable attaches to. Cant find it at the parts houses, not sure what one I need- so dont want to get the wrong one at a junk yard. I have found these GM numbers but think they are NOT for the NOVA. Hoping someone has a set to sell or can furnish the part # and location to buy?
