Measure the screw spacing on the engine. You can then go to the Macs Muffler website and look in the One Piece muffler section to see which engines have that same screw spacing. Once you have some engines, you can then check the Bisson Mufflers website and see which engine they have that matches. The GMS engine uses a common muffler screw spacing so quite a few brands will fit. For example my GMS 1.20 works well with a Webra 1.20 muffler and a Bisson Webra 1.20 Pitts muffler. Your .75 GMS may match up with a Webra .61 through .75 engine too, but I do not know for sure as I don't have one in that displacement.

Your Gms .76 matches the The Tower Hobbies .75 exactly. The two engines were made by the same company. I have a Tower .75 with the said pitts muffler sitting on the bench. That I no longer use. I repowered the plane with a .90. Tower used to sell the bison muffler. I will sell you a complete engine gp mount and muffler for the price of the new muffler. The engine is in good shape and runs excellent . It was removed from my shoestring this summer.
