Here's my spoiler badge still waiting for 50 degree weather to put the spoiler on... Actually still waiting for above freezing for that matter.... The interior badge is the same as the spoiler as well as the headrests.
I opted to get an SRT8 spoiler used off of the boards here. I liked the idea that it would have a nice fit and finish in the recess for the SRT8 spoiler. I'd guess I spent around $270.00 - $150 spoiler, $75.00 painting, and around $45.00 ish for the badge.
