I had my dealer (Shaheen Chevrolet) install it. As for in the grand rapids area, give Anna a shout out to see if she can help. She is at Sparta Chevrolet. I'd also think Berger can do it. Last but not least, there is a guy Rod Olemedo or something that has a totally custom Camaro who I believe had all that sponsored and done in the grand rapids area.
If you find the thread on last years Michigan Fbody Meet and great, you'll see his car and his apology for the burn out.
