Those upper quarter panel part numbers shown above are the part numbers listed in the original TSB. Both are superseded now. Ask me how I know...

The updated part numbers are:
Upper quarter panel trim (RH) = 84797933 (old # 84397869)
Upper quarter panel trim (LH) = 84797935 (old # 84397871)
Also, if your convertible was built prior to February 14, 2017, you are supposed to also replace the window regulator because the new upper quarter panels have an additional retaining clip. I am in the middle of replacing mine on the LH side, the new panel is supposed to arrive tomorrow. However, I am not replacing the regulator, I will modify as needed to get the updated trim panel to fit. at least that's my plan.

I've attached the original TSB on this issue.
