I'm not sure about mini graphics but we have an 09 Bighorn. I purchased the original graphics from Heartland. They will e-mail you a complete diagram with part numbers. You pick the components you want and they work up the price. Ours was $137.00 shipped. We had priced decals from local businesses and the prices were between 600.00-$700.00 We did the installation ourselves, but we were quoted $250.00 for the installation.
Hope this helps.
