Rear window seal questions

[unitt01]

So I was wondering if I could replace the rear window seal (#4) without having to replace the top seal(#5)...
or would the top seal be warped after removal?



Reason for replacement is my seal has somewhat "shrunk" and doesn't sit fitted anymore :(

The "top seal" is commonly called the lock strip and it's flexible so you shouldn't have to replace it. The #7 corner pieces are aluminum however and deform very easily when you remove them so I'd get new ones.
