A guy I work with has a small Makita 90 degree drill that i could
borrow to screw in the wood from the top, so it looks as if the
problem will be solved.
By the way, does this light need to be GFI protected?

If the fixture is subject to shower spray, it must be listed for "wet
locations". There is no requirement to be GFCI protected, unless required by
the fixture manufacturer.
Personally, I'd use GFCI protection regardless
