1968 455
 

I have a 1968 455 with a busted L side exhaust manifold. I'm having quite a difficult time finding a replacement. Does anyone know what years will fit on this or where I can find another? Most junkyards use a nationwide system and they are only seeing 1 available for $305...a little much considering I could buy another 455 for $500...

Any help would be great. Thanks!
