Just parts availability / getting to a shop? I always suggest 8 weeks (was more in my case but that was related to battery cutoff controls).
Time added from the insertion of insurance (who accepts liability, how long it takes for acceptance, how long for insurance to find/agree on a shop, how long to get the vehicle to the shop, how long of a backlog at the shop, how long for insurance to approve the quote / generate their own, how long for insurance to pay the shop for the work to release the vehicle)...who knows.
