Here's my writeup on this from the Berlina Register page. This is on my Super, and should be very similar, if not identical, on a Berlina.

This month's tip is about removing the stainless trim around the door windows on Berlinas and Giulia sedans in preparation for removing the window, or to get the trim out of the way for painting the car or replacing the window seals. The bottom "wiper" window seals, and window channel material, are available from Ranier Hurtienne (
www.alfahurtienne.de/) in Germany.
1. Begin at the door pillar end of each window. That is, start at the rear of the front doors; start at the front of the rear doors.
2. With a suitable tool, begin tapping the bottom of the U-shaped "vertical" piece off its flange on the door. Work very slowly and carefully.
3. Work your way up the vertical side, then across the top. There is a fair amount of back and forth and wiggling to get it to come away easily, without bending.
4. Finally, when it's free enough, you can pull the rear/front corner of the U-shaped piece away, freeing up the whole piece to come off.
5. Last, remove the separate base piece. I used a screwdriver to gently pry up, but if you have nice paint you won't want to do that.
6. Installation is the reverse of removal, with similar care and wiggling, especially if you have new paint. Some protective plastic or other guard over the paint below the window opening would be a good idea, as the sharp edges of the stainless trim can scrape the paint easily.
The interior trim comes out in exactly the same way as the outer trim. Mark each piece to ensure you know where to put them back in.
Notes:
* My trim was stainless and pretty resilient. If you have aluminum trim, you'd have to proceed like it was eggshells. I think it would be very hard not to bend.
* The tool I used was a Michelin bicycle tire removal tool, a plastic piece kind of like a bondo spreader, about 1" wide and 4" long. It has an S-shaped end that is perfect for getting in and catching the edge of the trim without mangling it, and without scratching the body edge. I tapped it with a big plastic mallet.
* The trim has a noticeable spring curve to it across the top, especially on the rear doors. This is true on some cars even when installed. I think this spring helps press the U-shaped piece down, locking the bottom piece in. So once you get the piece off, don't be alarmed if it has a gentle curve across the top. Kinks are bad though.
* When first starting, the pillar-end vertical part of the U-shaped piece can be fouled against the base piece. Tap gently up in the corner directly above, which can move the U-shaped piece up just enough so it is freed.
* At least on my 67 Giulia Super, the retention device at the pillar end of the bottom of the U-shaped piece is a tiny slot built into the door flange, with a corresponding dimple stamped into the back side of the stainless trim.
* On the front doors, I found two additional things were required:
1. To get past the vent window hinge, you must undo the two sheet-metal screws on the top side under the door seal, allowing the vent window hinge to come free. You don't have to move it much, and the screws are accessible by pulling up on the door seal.
2. At the front corner, the U-shaped piece wants to move down and get stuck on the base piece. So on these doors, after I freed the rear side completely, I pulled the base piece up and back just a bit to free up the front corner of the U-shaped piece.
* The "wiper" window seals inside and out are fastened to the bottom trim, inside and out, with metric steel staples. Remove the old staples, cut the seal to length, and fasten with suitable size new staples, or perhaps .040" or .080" safety wire. I haven't tackled the window channel material yet, which would involve removing the windows.
