Exhaust rubber mount

[mel]

I'm looking for the part number for an FX rubber-isolated exhaust mount.  The Kerker/H-D performance exhausts on my 1988 FXRS-Sp uses one of these OEM mounts.
The mount is 3 3/4" x 2", 3" between mounting holes, 1 3/4" round rubber center with 3/8" bolt hole through middle.

Appreciate any help.

If you mean the rear exhaust to frame mount for early fxr's,my 2006 vtwin catalogue shows vt 28-0229 ,the factory no should be 65780-82, should this be in the evo section ?.
