If you are having trouble getting those Phillips head screws out, get a
hand impact driver. 20 years of working on motorcycles demonstrated the
value of these inexpensive tools to me. With a proper fitting driver tip
and a few whacks with a hammer, almost any screw will come out.

I'm glad you said "almost" any screw. I've BEEN whacking on my impact
driver & all that's happened is I've bent the "flutes" of the phillips bit!

The part that these screws are in is going to be replaced, so
drilling-out is the next step.
