B/RB tri-Y headers wanted - used or ?

Looking for a pair of Schumacher B/RB tri-Y headers... putting the engine back into my 71 Roadrunner and need a pair of these due to a manifold crack... that and the cam I'm running really needs the exhaust to breathe more. PM me here and we'll talk. Yeah, it's my first post.... I know.... Thanks in advance for any leads!
