A new long muffler tail pipe has been released for use with the 79-B panel delivery, the 150-B station wagon and the 225-A special delivery. This new tail pipe carries the exhaust fumes still further back from the end of the body. The new pipe can be easily installed on old jobs by replacing the “A” design muffler with an AA-5230 muffler and then installing the new pipe by means of bolts and clamps as shown in Fig. 1087.
