I just got a universal catalytic converter and I need to get the flanges to weld onto the ends to put it in my exhaust. I've found the 2 bolt collector flange for the front but I'm having trouble finding a 3 bolt "male" flange that uses the stock ring gasket for the other side of the cat. The closest I can find is something like this. I'm looking for that, but with the spot built in to put the stock ring gasket.

 

This should work and it's cheaper too.
