You have to position the MFU/DMD just right, so the ring can rotate between the fuses on top and the guide wheels.
It helps to mount the DMD/MFU to the plate w/ velcro instead of the foam tape.
It is a mm or 2 taller, but that way you can re-position it easily.
Some guys leave out the mount plate all together to gain 1/4 inch of clearance or so.
But I kept it, and found it helpful to run wires underneath.
