S1 Doors - Help Needed

[turnamere]

I have noticed recently that the passenger side door doesn't line up properly with the rear clam and is just touching about half way down the shut line.

Quick read of the workshop manual and it looks like I should be able to slacken off 3 bolts, lift the rear end of the door slightly and re-tighten.

So, I head out with my allen keys - I can get to the rear most top and bottom bolts but there is no way there is enough space to get onto either of the front ones to loosen them.

Any one on here done this and have any suggestions how I'm going to get to the front bolts without removing the front clam? Is the clam flexible enough that I can remove a couple of the fixings and ease it outboard to gain access?
