Tower Hobby .75 engine
#26
The Tower engines were made by the same company that made them for GMS so I often used their stuff or substituted Pitts style GMS mufflers or made my own extension. Someone with a mini mill could knock one out for you.
In your case you want exactly the same spacing as the GMS .76 engines.

John, can you measure the holes on your muffler center to center. I was working on a project and thought I would need an extension and fabricated a couple. One fits OS .61 FSR and the other OS .61 SF. Both are about 1/2" thick, if either would work I would be more then happy to mail it to you.
