The Mercedes Sprinter from 2018 has a hinge option that isn't suitable for attaching accessories too. On the previous model Sprinter it was possible to modify these hinges - but this isn't possible anymore. In order to bolt a wheel carrier or rear door ladder to the hinges they need swapping out.
How do you know if you need to swap your hinges?
Do your doors open 270degrees parallel with the side of the van? If so - they need swapping. Here is a photo of these hinges.
Below is a photo of the correct hinges.

Where can one buy these? There are retailers who will sell you these hinges with a markup. Alternatively you can search the used parts market using the above parts number. The easiest way is to purchase direct from Mercedes - here are the details.
Email (DG-MTV-Bir-CallCentre@ballyvesey.com) with your parts request. They will reply with a price including shipping and you can simply pay them via PayPal following which they will post them to you. Easy as pie!
I have also requested that MTV put them on Ebay for us so you can easily order direct from them.
