O.K. My passenger side manifold developed a crack last week.

I've been hunting down the exhaust leak and finally found it. Now I need a passenger side Ram Horn Manifold. My ram horn is off a 72 chevy 350 2 wheel drive with the angle outlet. It also has the AIR injection holes too (although they are plugged). For uniformity's sake I would like the same type, but I understand I can't be too picky. The closer you are to Houston the better, Shipping is going to be killer I'm sure. Thanks in advance Guys!
