W Exhaust Manifold Needed 1974 Delta 88 w/ factory dual/ 455

My left exhaust W manifold is cracked and I need to replace it. Was hoping to secure just this, not a complete W/Z set. I see a lot of options out there including reproductions, but would like to keep it simple and as low cost as possible.

Any insight would be great

Thanks,
Ed

Cracked manifolds can be welded.

There should be many used "W" LH manifolds available.

All will have other flaws like pitting, bad threads, broken ears, etc.

Ok guys need some more help.

I just removed the LH manifold on the car tonight and it is a 412887 part # X manifold. I did some searching and seems that this is not too far off from the W Manifold that I thought I had. Would anyone happen to know if the outlet angles and overall measurements are the same? My exhaust system functions fine the way it is now, but I could have a new down pipe made up to accommodate the angle change w/ the W manifold I guess.

I notice Thorntons makes a replica X Manifold, but it appears to be based on the earlier versions w/o dual chamber center ports and it also has a heat riser on it.
