Hi...recently purchased a '82 Camaro Pace Car Edition with the 305 and automatic transmission. I have corroded mufflers (two on this version) with exhaust pipe inlets to the mufflers placed between the two mufflers. I have been unable to find replacements (original style) and am wondering if there is any available? I would greatly appreciate any input you might have, including originals, NOS or very good used. Thanks very much - Bob
