Agree with Dom.
Difficult engine access keeps me in check on my C8. Just the opposite situation on the C4 ZR-1. Full engine bay access without have to remove the Hood.

Re: TB removal and then some!!!

Hi Tom,
Good to hear from you.
The plastic piece is crimped in during manufacture of the nut. Doubt a replacement can be found. Better off replacing the nut with a good one.
