Also the bolts are part number 113-990-02-22 and eighteen required per bank. You can reuse the old ones. The specific socket needed is an E-Torx 10. If you cross thread it you won't be able to repair it because the thread is an uncommon M7 size so be careful.

would you advise new bolts to avoid stripping the threads?

The bolts are like 5$ each. Just reuse the bolts.

Clean the threads on the bolts, and the threads in the holes, and you shouldn't have any problems with stripped threads.
