Power brake booster

i’m about to replace a power brake booster and master cylinder on a 2000 olds. bravada.could someone please tell me if there are any gaskets that i’ll need to replace also(like where the master cylinder bolts on to the booster) thank you for your time and knowledge.

For a 2000 model car to need both a booster and master cylinder at the same time would be a pretty rare event…Are you SURE you need that booster?

But if you do, it’s pretty much just nuts and bolts…Some of the nuts can be VERY difficult to get to…(the ones that hold the booster to the firewall)…
