Exhaust manifold issue needs some help!!!!!

[blazercrazy70]

I have called a half a dozen junkyards for trailblazer manifolds no problem getting them but you can't get the flange or down pipe with o2 bung because they are removed before they get them. Need some help to locate these if anybody has any ideas. I thought getting the manifold was the hard part not the issue here I'm not a header fan but it may be the way I go if this keeps up
