67/68 barracuda rear window pull, reseal, replace question please

Hello, First time posting. Hope this is how it's done. Recently purchased another members 67 FB. Rear window leaks. Has a new seal. 68 style I believe? ( just looking again and looks like there is a locking strip so may e its a 67 style? Posted a
picture) and it has new 68 clips and SS trim. I do not think any sealant was used/added into the groves when installed so we (Apple Auto Glass) and I intend to remove, add sealant and pop it back together.

My question is, can this be done without removing all the trim inside that goes around the window? All the black shiny metal pieces? Looks like a big job to remove all of it?
Any comments most welcome. Thanks!
