Kombi door problem.

Had a bit of a mishap with my kombi today, the sliding door actually came totally adrift from the body and landed on the ground, I've rectified ( sorta 🙄&#128563😉 the damage which was minor and sourced a replacement bottom runner as I found the one on the bus was missing a bearing, I've managed to get the door back on but am unable to open it as the rear hinge U piece isn't able to swing out enabling the door to run past the body, I'm thinking that it was somehow "rearranged" when the door came adrift but can't see how to rectify the problem. Any one else out there had this problem and can give me any hints on how to overcome it?
Thanks
Don

Don,
A heap of "sliding door" posts here

in particular this one shows a "refurbishment of the sliding door rear hinge"
