There about three different sizes used for the actual locking mechanism , one very important thing to remember is you have to remove the cover cap at the end of the handle . DS has a key slot but some vans have a dummy cap on the pass side you remove the grommet around the edge of the door skin there is a torx screw that needs loosening before the cap can be removed . Once you get the cap off there is a very thin wire from the handle to the lock release you must release that before removing the lock itself I used a hook ended tool to pull the metal tang out of a slot that holds the cable . When you refit the lock use the same tool to pull the wire back into the slot .
