I have a N.O.S pair of factory 1972 A -body 340 dual exaust pipe hangers. Never been installed on a car these are OE have some flash rust from sitting forever but no pitting will clean up to look new again easily. Im going with larger pipes these will not work. $ 150.00 shipped to the lower 48 states and Canada. Pay pal please pm me if your interested, thanks FABO.
