its two socket head cap screws. you change it every 2 years when you change the bellows.

the casting comes with a new rubber gasket.

Does the top of the drive have to be removed to replace it? will I need any other o rings or gaskets besides the neck gasket. thanks

No, and you can do it with the bellows in place with a cut down allen key (a major pain in the butt, however you can do it), however its much easier to do it with the gear box off or the drive off. if you take the gear box off, you need the large o-ring.

in the volvo-penta DIY stickies, there is a writeup on replacing bellows and just pulling the upper gear box.
