NOS 3983066 muffler fitment
 

I acquired 2 NOS 3983066 NOS mufflers, I am certain that they fit a 70 to 73 z28 and 70 to 72 SS camaros with duel exhaust. I want to put them up for sale and wondering if the firebird trans ams used the same muffler?

3983066 is a 1970 Camaro Z28 or SS396 transverse muffler

Ron, What are you asking or what have they brought

Are these the Mufflers with the Small embossed W on them and square top corners.

I bought several of these YEARS ago at Carlisle......but mine I believe were New disgarded on the assy line, due to bent ends pipes and later sold by GM to ????
