I have a set of nylon beam mounts that measure 1 and 5/8 inches center to center and they are 3 inches long. I was cleaning up and found a set of aluminum mounts that are 2 and 1/16 inch center to center and they are about 2 inches long with 1 and 3/4 inches of usable flat surface. The mounting beam on the aluminum is off set from center. Let me know if these will work and I can send them to you. Dave
