Stihl 404 rim help please

[dsell]

What's the difference between these two Stihl rim part numbers? (besides the last digit)
0000-642-1206
0000-642-1207

 

[big t double]

nothing really. if you would go to a dealer and try and order the 1207 it would supersede to the 1206

I am just guessing here but if they are both 7 pin standard spline sprockets it could be the cut-out section in the spline area like in the pick you posted. One may be flush the other like the pic above.

Good eye. I didn't notice the cut out. What is it for? It's smooth on the other side.
