I've got my new 5.3 l with camaro exhaust manifolds in my CJ-7. Trying to find a solution for exhaust flanges. The 3 hole manifolds are odd shaped any input greatly appreciated.

 

I've heard of guys making their own flanges, using the manifolds as a template. It would be pretty easy if you are into fabrication. I think someone sells them too but I can't remember where I saw or heard about it. Of course that was well after I made my own.
