Corvette Performance - Need a factory muffler for my 2000 'vette and a source for the removable roof

Where can I find a factory muffler and a replacement roof panel? new or used does not matter!

also what are the dimensions of the muffler inlets and the muffler itself for a factory muffler on a 2000 vette? are they the same muffler as are on any ls1?

no need for muffler, problem solved.. need to find a source for a roof panel, air conditioner hose, and the abs control unit..
