Shifter linkage

[Viper2172]

Need some assistance guys. The shifter linkage on my son's 2002 GZ250 came off the shaft the other day. Everything is still intact and I briefly had time to look at it but when I ran my finger on the outside of the shaft to look for a bolt hole, I didn't feel one. How is the linkage held in place? I looked on Partzilla for the diagram and it wasn't very helpful.

Any and all assistance is greatly appreciated.

Thanks,

Ray
