Its a ton of work to get the OEM side view mirror to work with the G28 door skin.
Wasn't happy with the way the body lines were from the door to the back of the car on the modified drivers side.
Had to cut the mounting system for the door handle and lower it 1/4 or so and welded it back together so the handle and lock aligns with the existing holes in the door skin.
After a bunch of this and that the door lines up better with the body.
Im still not 100% on the OEM mirrors on the G28 but Will move on to the passenger side.
Worse case scenario, I need 2 G28 door skins.
