thank you @erik_squires . What does VC stand for?
The fasteners for the tweeter are exposed right in front of the speaker and then there is a triangular plastic guard covering the dome tweeter with more accessible fasteners.
I saw a few you tube videos where they show how to wick out the old fluid. One video demonstrated using a piece of masking tape, folded in a way that the adhesive was on both sides of the outside in order to remove the old ferro fluid. The other video I watched, they just used like coffee filter paper one little piece at a time until there were minimal dark stains on the paper. Then they took more of the coffee filter paper with some rubbing alcohol (or pure grain alcohol?) on it in order to get it even cleaner before they put the fresh ferro fluid in.
