Show Chrome Rack and Custom Dynamics Brake Light

Alas and Alack, in dry fitting the Show Chrome rack to the trunk of my RT, I found that it won't fit because of an interference with the Custom Dynamics High Mount Brake Light that I've had for years.
Not to worry.
Evidently, I'm not the first.
Show Chrome makes risers for their rack that will lift it 5/8 " high, enough to provide the necessary clearance.
This is not a major problem, I just want to give a heads up to anyone with a similar configuration.
