Which exhaust manifold works? Went from 318 to 360. 1970 Duster

You can save some cash if you get a 73 driver side 340 manifold , and for the passenger side use a 92-96 keep grand Cherokee manifold non smog same outlet size as the 340 actually it's 2 1/8 but pretty close
Thanks for the heads up. Will keep in mind in my search.
