http://www.tntmusclecars.com/manifold.html Try this link or Thornton Reproductions web site......The manifold you need is sold by them....Didnt I say so before???...A little searching should have led you to the right manifold......If not a junkyard manifold should be easy to find as the same one was used from 65 to 70 on most every full size BB Olds.
