i just noticed a small plastic cover on the ceiling of my retractable roof in the ceterline, a few inches forward of the driver's head...of course, being the curious cat that i am, i tried removing the cover...one of the "posts" that secure the cover to the roof snapped off...it seemed really brittle...i didn't use much force at all...anyway, the cover won't stay on securely anymore, and i'm worried that it will fall out when lowering/raising the roof...i've looked thru the manual and can't find what this was covering...it appears to be a keyhole for manual operation of the roof? i'd like to replace it, but i'm not sure what to look for or order...in the mean time, do you think some double sided tape would keep it from falling off when operating the roof? thx
