after reading the 'how to' information on this site, my 14 year old son and I decided we could tackle the deteriorated mounts. Used the prothane kit. only changed the b and c locations that were in the expected extremely bad shape. We took most of a day. Able to do it with just a breaker bar but an air wrench would have saved a lot of effort. Not something we would have done on our own without the excellent info available on this site.
