I had to remove the chrome on a vent wing on my '66 Le Mans. A two week soak in kerosene in the parts washer softened the setting tape back up so it could be pulled off with reasonable effort. As the vent wing chrome wraps around 2 sides of the glass, it was perhaps a bit tougher than the Firebird quarter glass would be.

I finished installing my 1/4 windows and thought I'd close the loop on my original question.
I ended up wrapping the windows up in bubble wrap and sitting them outside in the blazing FL sun. After a couple hours the trim just pulled right off. Installing the new trim had me stumped for a bit, but I got the rubber inserts warmed up a bit and applied just a bit of silicone spray. The chrome trim slid on with little effort.
I put the tape on the glass dry, applied just a small dab of silicone to the outside of the tape, and then pressed the trim on. I'll check it -- hopefully that will stay stuck
You may want to go back and redo the tape again. The silicone will act as a barrier between the adhesive and chrome. The adhesive is probably adhered to the window though....so that's good news.
If you don't trust Vikki, you should trust me.....I develop silicone release coatings and adhesives for a living.
I used some butyl tape i had leftover from my FGF windshield install to fix the quarter window trim weatherstrip moulding on my 69' cutlass (was falling off)and it's been almost a year now and is on there ROCK solid.
