Morris Minor Owners Club

the roof on my 66 Traveller was incorrectly fitted in Portugal.The guttering is between the roof and the wood screwed on with self tapers.
Would it be possible to remove the roof without disturbing the wood to refit with new T seal and guttering in correct position?
Thanks

Depends I guess if there are big 'screw' holes in the roof now ?

Is there any other type of fixing under the rubber seal apart from the bolts that pull the rear roof and cab roof together?
So that if you undo those and remove screws around edge of roof its free to come off
