front mount is simple its the rear one thats a pig its difficult to get too and really shouldnt be attempted without axle stands and a proper jack. local garage should be able to do them for few notes cant be sure but the standard 8v mounts are about £10-20 each and 16v and rallye ones are more cant say for sure someone on here should be able to tell you, i know someone on here who had front and rears changed for £60 anyone had them done from a garage got a rough quote???
