That sliver tube about 1 1/4" long and hollow it the post for the off side without the servo saver at least I think. There are 4 cupped washers and I have no idea what they are for. I would post a picture for you but I am not at home and the computer I am using is the computer from HELL.
On most of the posts where people are having problems with FLM products there is no responce from the company. Getting any help or information out of them sucks.
I used the four cupped washers for the screws that mount the chassis to the rear bulk head four more would of been nicer so i could do the same in the front
