Still working away on my '61 270HP CU 4 speed mid-March 1961 car. The TIM&JG references direct flow round mufflers but without any part numbers. These are pics from the front, middle and rear of the exhaust system. What's my best course of action? Are the round mufflers that most of the vendors sell zero point deduction parts or is there an obvious source for correct repro that would be a better choice? Other than correct clamps likely anything else I'll need to purchase?
