OS FSR 40 Muffler Screw Size - Found

Hi all. So I just have a little question regarding my FSR 40 engine. I got it with an aftermarket muffler and a half of the original. I recently found a travel size moussecan than fit inside the original half. I now have my first 'moussecan muffler' that I would like to try running. So now I would like to install it and run it on my engine hopefully this weekend but am missing the muffler screws. So if anyone here would happen to know the size of the screws, I can hopefully pick some up by the weekend. Thank you.

Even with the stock muffler the 40FSR was not that loud.

Saying this since I personally would not want to increase the mass hanging from the bolts into the case too much.

IMO, even though that muffler mounting style was common to my other favorites, Fox, it was the only weakness to an otherwise outstanding engine, (great carbs, as well).

At one point had at least 6 40-45 FSR's, one sporting a tuned pipe, and although pretty much out of 2-stroke keep one in storage for nostalgia.

Yeah, before almost all two stroke engines went to bolt on muffler, the strap method of attachment almost never caused the damage to the exhaust boss on the engine head in a crash.

With bolt on mufflers, some people cut a groove into the circumference of the exhaust bolts to reduce the bolt's strength in order to increase the chances of the muffler breaking away cleanly from the engine. If you do this cut the groove at a location along the bolt where there is still 1/8" or so of the bolt shank protruding after a crash separation so you can remove the bolt stub with pliers.
