T-top End Cap/Weatherstrip question
I expect that the molding needs to come off in order to inspect the attachment and craft a new weatherstrip, but I've never tried it. (I'm not sure if the molding is siliconed down to the roof or not. If not, it should be an easy thing to deal with.)

The dealer I visited actually had them in stock! The parts themselves run less than $1 each online and the dealer I visited charged me $1.86 for one and $1.95 for the other.
They were listed as parts in group 12.812 with the molding, but are not depicted in any exploded diagrams.
I was able to get the new caps on with great results, but don't think I have everything down 100%. Maybe the next person to do this can put together a sticky-quality write up? (There are no directions on how to do this in the Factory Service Manual.)
I've attached three pictures. One of the caps laying flat, one from the side view, and one of the center molding off.
On the parts: they are very similar, except for the molded curvature. (See the side view picture.) I didn't note which one was which from the dealer, but I'm 95.9% sure that the flatter profile one is for the rear, and the one with more curve is the one for the front.
When I took off the center trim, I got a really nasty, sticky surprise. (See other picture.) The molding uses a single sided 1" wide urethane foam tape to seal the screw holes and keep things from squeaking/rubbing. The tape's adhesive had liquefied over time and the tape was starting to separate from the Mylar backing. Things would have been better if I was wearing rubber gloves at the time. The adhesive cleans up reasonably well with rubbing alcohol.
If I had a little more time, I would have ordered replacement foam tape and cleaned up everything really well. Instead, I carefully re-lined up the old tape and it seemed to hold together well enough. I think this is the replacement tape: http://solutions.3m.com/wps/portal/3...glPL95HS7G7Hbl The catch is that I could only find it in 36 yard rolls for $50-60. Hopefully someone else sells a comparable tape in a smaller quantity.
Once I had the molding off, I found that the old caps were spot glued on. I was able to scrape everything clean and then used super glue to bond the full width of the cap on with a very thin layer of adhesive. The bond held rock-solid and worked really well. The only thing I wished I had done would have been to put tape across the top of the molding and across the top of the cap to deal with some oozing out of the top of the assembly where the two meet.

Thats awesome...you know I looked in 12.812 and looked right over those caps since they are using the same call-out number as the roof bar #3 in the GM parts catalog.
