Can I please have some help please I had a new vinyl roof fitted to my grande the trimmer used the factory measurements out of the book to position the stitch join and I’m worried something is wrong because under the trim at the rear there looks to be a factory formed gap under the trim for it to line up with ? I just want to see if this is correct or not , can I please get a photo of the area in the photo so I can see the vinyl raised area with the joint stitch under the trim , thank you
