What sort of equiptment do you have access to? You usually have to take off the hubs for the front ones, and hit them out with a hammer and the new ones will need pressed in. The rear ones are in the rear drum and usually need chapped out and in again with a hammer and small punch. Judging by the age of your car they might be thight to come apart etc, I would get a garage to do it, unless you have access to a garage or someone with tech knowledge. Thanks Gary
