Idler Bracket

Have my Custom 600 shifting great now. Needed a shifter stop under the shift lever.
Now the idler bracket fell off the frame/motor and I see any way to mount it back on. I believe something else is missing, maybe a bracket or a shim, because it does not line up with the only two holes in the block. Also, I don't think it has the original motor.
Would anyone have a detailed pic or information that could help me? Thanks

has diagrams if you input the model #
