I new to these cars, but this seems like a good deal. Has anyone tried them out?
Are they easy to install?

thanks for the info

Lets see, you have one post. You were clearly on the 3si board which is loaded with technical experts and the person selling the item you're asking about.


I think this may be one of the most slam dunk pieces of spam I've ever seen.


Good-bye.
