DW 6600 Rubber Cushion – Part #??

Looking for a source/part number for a DW 6600 I'm trying to resurrect. It's missing the rubber 'cushion' that sits behind the module, between it and the case back. Included is a pic of said part (the rubber piece more or less in the middle of the photo).

If unavailable, anyone have any thoughts other than using some type of rubber to shim between the module and case back? Without this piece my backlight doesn't work as the module shifts front to back.
