Using a standard harmonic balancer puller with 3 bolts that are just a bit too large for the 3 openings if possible., Tap them with a die large enough to get a decent grip with the bolts and remove it like any other.

Page 5-101 on this website will be insightful of the fuse placement. http://www.vadengmpp.com/owners-manual/buick/2004-Buick-Regal.pdf It is recommended to remove both fuses if you are working near the air bag. #5 fuse should be removed when working near the dash. You will have #1 - #8 fuses that are the same size on one side. It would be good to remove both fuses just to make sure you are taking safe and preventive measures. Good luck!
