Need a Dimension. Rear Case bushing on YZ400-450F

I am looking for a dimensions for the case bushing that the pivot bolt runs threw. I dont have any bushing in my motor to measure of off so I figured I would put up a post and see if anyone had a motor out they could measure them from. The only thing I need to know is how much the bushing sticks out on each side of the cases.

Here is a link to a parts finder that shows what i am talking about, They call it a "Collar" The # on the page is 23.

Thanks, Nick

The thickness of each of the collars is half the difference between the gap between the installed swing arm bearing sleeves and the width of the rear of the case where the collars go.
