Cross Referencing Manifold Casting Numbers

The exhaust manifold on the passenger side of my '67 Pontiac is cracked and I would like to replace it instead of soldering it. It has to come out regardless of what I chose to do, so might as well get a "new" one.

We have been looking to match the casting number to something out there, but so far, no luck.

Does anyone have any suggestions on where we can look to match these numbers? There must be a website or something somewhere....maybe....

From what I can see (I have to look with a mirror and there is quite a bit of rust on the manifold), the number for the cracked exhaust manifold is 933778 or 958778 or 938778.

Engine is 67 Pontiac 400 cid.

Thanks,
