I'm installing the DGL in my 98 foreman & the instructions say to remove the thrust washer from under the outer spacer.I have no washer under the spacer,all plates have groves cut in them so they are part of the locker.I do have 2 washers on top of the outer spacer.Are these the ones that get removed & were just put in the wrong place when the locker was assembled.I really need to know if when you guys installed yours did what did the washers look like,smooth or grooved/notched?
