Thank you for those pics.
This picture is from the Reverse Loc/Out Instruction Sheet. Compare washers and spacer. Looks to be the same...
Are the bolts in your picture in zinc finish? Hard to tell, but looks like it. It appears the bolt in this second picture is, as apposed to the shifter housing in black finish.
On the other hand, details like this could have been changed during the first day or week of preparations for the up coming race. But it is interesting to see. The more info pointing in one direction, the more likely it is we are closer to the right answer.
