As my son's 1972 340 Cuda is on the rotisserie , question has been brought up about brackets to support the dual exhaust thru the rear valance.Car came with a support by the shock brace on passenger side and a bracket thats mounted on the drivers side just up from the rear floor. Some people say the brackets are correct others say i need to add the bracket to the floor area. car is not going to be a show car, just want correct supports so we dont have to add at the tail end after bottom is painted Thanks.
