Re: Chirping sound in rear as 68 idles
Probably not the same issue but My parents bought a new Impala in "68",327 with a turbo 400 trans,it developed a squeak or chirp only at idle. It turned out to be the shift linkage(column shift),the end of the bell crank that went into the bracket on the frame rail would move slightly in and out as the engine idled causing the squeak,some grease occasionally stopped the noise.Also remember Mom having the $hit scared out of her when the broken motor mount caused the engine to lift and motor to accelerate,wasn't long after,the recall came out and the safety lift cables were installed. Grecian Green Impala custom,manual steering and brakes,Mom had a tough time with the steering as the steering wheel diameters were getting smaller around "68".If you suspect the erxhaust I bet you could put a prybar or a simular item into the tail pipe(s) at idle and put some pressure on it and see if the noise goes away.
