They had a local shop do the install. The bump in the roof is extended farther forward and becomes less rounded, so the sunroof can slide over the A/C unit.
Contact them from www.earnhardts.com and hopefully they will share their source if you are outside of AZ or already own one.
If they don't respond, I'll take a trip to see my salesman and find out for you.
