Intel Xserve and Center (2 post rack) Mounting.

I recently received my first Intel Xserve. With past g4 and g5 Xserves I have been able to center mount them into a 2 post telco rack. The new rack mount kits for the Intel Xserves seem to only support a 4 post rack. Has anyone had experience center mounting one of the new Intel Xserves? Is there a third party center mount solution? Thanks, any input would be very helpful.
