I have a 1988 rinell with a 5.7 cobra engine. I pulled the engine to replace transom and stringers. In the course of doing this I snapped off a few bolts on the transom plate that were stainless. It's at a machinists now having them removed. So I decided to replace the gaskets on the osco riser that is rear mounted I broke off one bolt tried to drill it out but the bit broke off necessitating that being removed. That manifold is heading to the machinist. Okay so now i am searching for the exhaust gasket for an 88 cobra 5.7 with the osco rear riser. I have the riser gaskets but having difficulty finding one that matches. The descriptions say for bar marine or some other brand of manifold. I have seen a bunch but don't want to order the wrong one. When I get the right one is there and sealant applied? Thanks in advance.

I would have bought new manifolds

Get some gasket material and a small ball peen hammer and tap one out using the riser as the pattern. The old time way.
