I had a customer who has a rear door drilled open on a transit van, Garrison Locks sent me out the same day a repair plate to cover the damage, it fitted just right and secured the van door. These were well priced too, only about £50.00
Tip for consumers: I think that if you type in "repair plate" all these plates come up, was a little tricky to find the right one initially as I nearly got the vivaro rear door plate, then realised the picture was different to my van.
Products used: I ended up buying a side door repair plate for a transit van mk8 . Apparently this is now a common problem and they have a product to cover the damaged area.
