Most swingaway wheel carriers have a plate which pick ups on the existing holes in the rear door..
If you have a new door without holes already in your choices are to drill holes in the door or use a pick up version.
However pickup versions are illegal for a rear door if it has seats in the rear as the wheel carrier has to be open first from the outside.
Choices are in descending price order, Kaymar from Outback Import in France, Sonic from Allisport or Nakatanenga from 4x4 Overlander. None of those require holes drilling in the body work.
The Safari Equip wheel carrier for pick ups require holes drilling in the bodywork.
Swingaway wheel carriers without drilling body bodywork, but picking up on holes in rear door your choices are the Nakatanenga or Safari Equip single pivot wheel carriers.
Picking up on holes in rear door and drilling holes in bodywork? A myriad of versions available from Safari Equip, Mantec , Britpart etc etc.
