3 pieces of original SS 396 Camaro exhaust

[68z28kk]

Back in '97 I bought a 396 Camaro that sold new in Arizona and had baked in the Arizona sun. I retired in 2000 and freshened the camaro up with new Lacquer paint and fresh interior. At the time I found and purchased both GM over the axle pipes and the left tailpipe in a black anodized type finish with GM part numbers stamped in them. I think they need to go on a rarer car than mine. My question is would their be a demand for the three pipes I have, That are still like new with only 150 miles on them since installed on my car. These were new car take offs in '69. Clint
