EGR tube/pipe

I have a 97 chev tahoe. I had to rebuild the top of my block, in the process I managed to twist my egr tube connecting from exhaust manifold to intake manifold. I have been looking for this part for 6 months. The local dealership told me this part had a national back order and the company that produced this part is no longer in business. My question is what do I do from here. I saved the connections now can I make a part to work using these connectors, If so what dimensions are they. Also what should I use to make this. Also every where I look I cant even get a pic of this part, or find any info online. I really hope you guys can help. Thanks.
