Need help. I recently replaced a cracked exhaust manifold and have a leak at the connection from the manifold to the converter. I looked in the jeep manual and found that there is a seal ring for this connection. I bought the seal ring but it doesn't fit. The manifold has a donut shape to it already and the convert has the inverted donut shape. The old manifold when removed did not have a seal ring on it. Has anyone ran into this while working on their Jeep? The Jeep is a 99 Wrangler with the 2.5 liter engine. Any recommendations on how to fix the leak?

I looked up the exhaust system in the 1999 Mopar parts catalog.  The 4.0L uses a P/N 52005431 exhaust seal.

Your 2.5L does not have a gasket listed.  I put together a PDF with the intake/exhaust manifolds and all exhaust pieces.  Note that your engine application is the EPO:

This should help...
