‘67 Barracuda FB quarters, extensions, and rear glass

Now this changes the game for me with the full quarters. I’ll have to pull the rear glass. I’m sure it’s a pain is the ***. Gasket is shot anyway. Should I upgrade to the 68-69 style with the clips? The locking Mylar stuff broke like glass as I was removing it. 51D5E2B8-8485-439F-B9C5-389EC5636AED.jpeg902555B1-8EF2-4F60-A873-F0CF856E19BA.jpegE596A0EE-3DEA-406C-8A41-F14D7A5A5443.jpeg
