Thanks for your offer, Rainedave, I got your PM, but it doesn't look like it'll work...

As you can see, my engine is a bit dated... no mounting bosses for a muffler. I guess I'm stuck with the old wrap-around. Maybe some of you ST Historians can tell me if this is the correct muffler for this engine (mufflers were an option when this engine was made). I also wonder what would happen if I plugged the nose end of it so that I could stick this on a vintage aircraft sometime.

Thanks again for your offer,

Bob
