Does anyone know what spur with fit a 1/8 scale clutch bell , the stock tmaxx 3.3 spur won't mesh with a 1/8 scale clutch bell and I can't find one that will work. I was thinking about the revo mod1 spur set up but I don't know enough about it. Thanks.

Most 1/8th scale buggy/truggy/mt clutch bells are Mod 1 just like the revo spur.
You could use the revo clutch bells, the only problem that you would run into is the revo spurs are a smaller diameter than the tmaxx spurs, and you may run out of adjustment of the engine to set the mesh correctly depending on what spur/bell ratio you choose.
You can elongate the chassis engine mount slots to move the engine closer to the center line if needed.
Other 1/8th scale mod 1 bells will work also with a stock setup, but you want to use the narrow bells so the contact patch between the spur and bell gears is not offset or that the bell portion does not extend out too far and rub the spur.

Snook Man, I have a 17t cb 1/8 scale mod 1 pitch, the issue I'm having is finding a mod 1 spur to fit the gray 3.3 trans, I was going to put a revo spur on it but they only make it up to a 36t I think, would that combo work for me?. If not what spur will work? The 1/10 scale clutch just doesn't cut it with a big block Dave at BUKU recomend I go with a 1/8 scale clutch set after I was having problems with the 1/10 scale set.
