All original stainless on the interior panels need to be transferred to the new assembled door and rear 1/4 interior panels and any rear arm rest with stainless. Carefully bend the pointed metal tabs to not break them so you can reinstall them. I had my local interior guy install my stainless on the new panels (but it can be done just not easy work to install them correctly)
Also the metal top rails need to be saved and sent in to Ciadella to be used on the new interior side panels and rear 1/4 interior panels (
do not use repro top rails..... -they will not stay in place and fit is not as good as the originals...)
For door panels I recall that 61 - 62 bubbletops do not have stainless on the top of the doors and rear 1/4s (like 2 door hardtops and convertibles)
There are these felt kits(see link below) that are necessary at a minimum for the interior door and rear 1/4 panels. These kits have the
chrome beaded felt for the door and rear 1/4 interior panels + the rubber felts for the top of door and rear 1/4 stainless. this is set is a 8 piece felt kit (4 for interior and 4 for exterior)

I asked Ciadella Interiors about these felts and made sure they installed the new chrome beaded felt on the interior panels ("with large staple machines like they were originally installed with staples"....)
The new rubber seals for the top of door and top of rear 1/4s rubber stainless where sent to me to with the new interior panels for me to install the new rubber seals on my stainless.
