I didn't get too in depth with the dealer about the parts that would be involved during the repair, so I'm not sure about what constitutes a track repair or replacement. Regarding wait times for parts, they simply sent me a postcard (about 2 weeks wait) when the part came in and I brought my car over the next day. They said that if they hadn't broken my moonroof glass, they could have had the car finished the day I brought it in. It ended up taking 3 days for them to get the new moonroof (from a sister dealership) and install it.
