Have your dealer read recall notice #05112 ( and ALL revisions of that document). For example, bulletin #05112C, issued June 2006.
Not all 2005-2006 Corvettes are affected.
IMPORTANT: Dealers should confirm vehicle eligibility through GMVIS (GM vehicle inquiry system) prior to beginning repairs.
I had the roof on my 2006 Z06 inspected and repaired from an authorized Chevrolet dealer, and they used 10 each of bolt part number 11561612, and adhesive part number 88861400 in the repair. Again, I remind you, I have the non-removable roof (but it is) C6 Z06, and the repair tech inspected my roof, took the GM prescribed measurements, and replaced the 10 bolts. These bolts are a one time usage commodity since they have a pre applied coating on the threads.
Hope this helps.
