Rear left door is leaving a small gap when closing and it looks like these screws need tightening. I think I need a security screwdriver of some kind, but I don't seem to have anything like this, and can't find it online. Can anyone tell me what it is and where to get it? Thanks in advance.

@Cairus Thanks for the help. I will look for similar on UK site, as German Amazon will not deliver to me here.

They are triple square splines. I got a cheap set from Amazon and so far they have lasted very well.

There about £14 on amazon.

Thanks, I ordered a set on Monday night and did the job yesterday. Door is now closing fine.
