Sanderson DD7 header issue

I bought a set end of May. Looked promising at first, but when bolted on steering shaft will not clear. Going around would require 2 double or 4 single joints and a support. I was advised against that from several sources. I was told they would take them back, but I have 2 people interested in them. Does anyone know if the Dorman cast exhaust manifolds from Summit are the 2-1/8" outlet size?
