Very nice work, it's looking stunning.
One observation, though: I could be wrong, but I don't think the screen seal trim is just decorative, I believe it locks the seal and screen in place. That was certainly the case with my MG's 'Bermuda' Hard Top (in the background below) - when I restored it, before the trim strip was fitted the slightest pressure would flip the seals and let the perspex pop out.
If it's the same on yours, your rear screen
could pop out if you drive it to the testing station without the trim fitted.
Keep up the good work!
