John, On the smaller grands I have had to use the rail cover on the player system to secure the lyre supports to. Usually I'll use the hardwood lever mounting blocks that are removed when the system is installed. Find the appropriate angle for the support rods, drill or chisel whatever holes needed to accept the rod and shorten the rod length. I fasten the mounting blocks to the rail cover with liquid nails and screws cut to length so their just enough thread into the sheet metal cover. If there is enough room I'll install a adjustment screw inside the block to adjust for looseness as time and wear necessitates. Hope this helps.
