    My plan is to epoxy in a fitting with a petcock valve. The Teflon tape works just fine. No leaks. If there is any leaking it would be so small it really wouldn't hurt anything.

    Interesting - when did draining the mufflers become part of the winterization process? You would think the drain plug set up would be more robust. I don't even think my 98 has a drain plug and if it does it is lying on the floor where I couldn't get to it.

    Here is the fix for the problem. Get your self a 5/16-18 self tapping bolt from Fastenal (item #32416)(5/16-18x3/4"HWSLTCS). Get a "performance tool" 125 piece rubber grommet set off ebay (item #5214). Remove the old stripped out bolt that you use to drain the water out of the muffler. Using a flat blade screw driver, reem out the hole until you are able to thread in the new self tapper. Put a rubber grommet on the self tapper. Tighten down (but not too tight). No more leaks!!!

    Why not use a metal roofing screw? Already has the sealing washer.
