Just checking back,
can anyone fabricate the "roof spoiler" with or without functional lighting?

or

know where I can get my paws on one?

Here is a copy/paste link to a thread in reference

I'm going to have some made, if you are still interested, you can contact me at this address. gmgwplus@yahoo.com
