Does anyone know a good shop that can install a Kaminari Flush Mount wing? I had a shop do it back in my home town and I just now discovered it lifting up from my hatch. The guy did a ____ poor job and now I need to find a place in the Greensboro, Raleigh, Fayetteville, etc. areas that can help fix my problem. All I really need is to find the bolt size I can use that fits in the existing grooves that come pre-installed on the spoiler.
