A ferry permit will require a Mx sign off, and if you don’t know what your a&p did in those inspection panels, ( I’m assuming that’s what you meant by “covers”.); then by flying it… well you get the idea.
Not sure how or why or even IF you’re crossways with this mech, but I would be cautious in attempting to fly this aircraft.
Is there another mech you can get help from, if you are in need of another mech?
The spinner bulkheads, without spinners, will fold back under rpm from the prop. I wouldn’t run it up to high rpm’s without spinners.
As an FYI, a ferry permit will allow one to fly an “unairworthy” aircraft.
