URGENT help needed :( -DIY springs

[Masteraal]

Im just doing my springs ive managed to do the rears... after a while

but i just need help with the fronts.
the part in question is:

Next, pry up the rubber dust cap.


Under the cap is a nut holding the top of the strut assy., to the shock tower of car. Get your 17mm box wrench and loosen the nut while HOLDING the center from spinning, with a 6mm allen key.

Once loose, remove enitre assy., from car.

how do i remove that bolt? i cant seem to get a spanner ot a wrench in that small space?

is there a trick to doing it?

P.S. I havent done this part :
We need to remove the (2) Sway Bar end links, (2) Strut bolts, and (1) Brake bolt.
Follow the bolts with sizes marked, and remove.. any order is fine.

yet cos i was concerned i wont be able to remove the wiper section and that bolt.

any help would be appreciated
