So my husband let his 1978 Mustang sit for a really long time and now that we have money to finish working on it we took it in for inspection. Our mechanic called and said the E-Brake is not working b/c there is a part missing. He does not know what this part is. He said there is a part that should hook on to the E-Brake cable and that it belongs between the steel rod that goes towards the back of the car and the E-Brake cable. Can someone please tell me what this part is? It's a 1978 Mustang II Ghia.
