I don't know anything about Civics and Acuras, but on the Saturn it's really easy. The knuckle assemblies are the same on all S series cars, so you just get the calipers from any year S series and bolt them right up. Reuse the same hub. I got some at a junkyard, bought new ones and used the junk parts to get the core charge returned. Watch out for the parking brake cable though, it may not line up. You may have to get one from a junkyard or buy the OEM part. Hardest part was removing the drums, hub and backing plate of the drum from the hub, since my car's seen a lot of nasty winter conditions. Lots of PB blaster, persistent hammering and eventually it all comes apart. Give yourself at least a couple days to do it, this **** never goes how you plan...
