Mk 8 Transit Custom Barn Door Alignment

[Dave46049]

Hi, wonder if anyone can help.

The barn doors on my transit are slightly ouot of alignment, the driver side one sits a bit further out than the passengerside one when the barn doors are closed.
Rainwater does not get it and still runs away, but from the outside it looks like the one door is unlocked and I don't want any idiots trying to force it open.

I was hoping that you could adjust the doors the way you do on flatpack furniture ( thats me hoping! ).

Anybody else hd an issue like this, I don't really want to take it to a garage to get sorted if at all possible.

Thanks
Dave
