Intake Manifold

Hey everyone. I started breaking down my 1966 429 and found that the intake manifold is toast. It''s got lots of corrosion, cracked, and just basically beat up. I''m looking for an after-market manifold but am having a hard time finding one. Edelbrock, Summit, Jegs, and many of the manifold manufacturers don''t make one. Does anyone know of a company who makes one or if I have to, a place that sells good remanufactured ones? All help is greatly appreciated. Thanks.

 Aftermarket intakes for 429 have been out of production for years. They do occasionally show up on ebay. Searching web under cadillac racing or 500 made yield source.

man i beat thats a sweet ride, put up a pic if you can.
