sliding door

Have jus through a l400 and recently it started popping of the track, just the centre arm. It does have and extension arm mod and it also doesn’t make it fully down the track without hitting the re fender. Any suggestions to an easy fix for both? Thanks in advance!

anyone know where I can buy a sliding door extension? Also is it the same as the L300 sliding door extension? Thank you

Does anyone have a spare sliding door electrical contact? I asked Steven at Rising Sun and he's still searching for one at the moment. This is what mine looked like when I pulled off the interior door panel. :( OR can someone help me identify the order of the wiring going down the connector...

It closes but then pops back out... it like the electric locking part is not engaging. It also kicks out the electric step as well. That I could shut off, but the dash shows the door is ajar. Any ideas on how to fix it? Thanks, Ben
