I just sent Restoration Specialties a sample of every window seal in my Aero doors, plus my tattered divider channels. Window channel, inner fuzzy strip at the door top, outer fuzzy strip, window lift channel rubber seal and the covered divider channel at the back of the wing window.
They're matching everything except for the riveted on OEM window channel clips which I can use 3M double side tape for, and the window lift channel seal which I think I may have found a substitute for.
They do not have Aero type covered window divider channel but can recover them in house, and re-rivet the mounts.
