has anyone used this bushings on their jag? im replacing the lower shock bushings and the swaybar bushings and saw those prothane ones on ebay. the thing is the lowershock bushings i see does not specify if they are front or rear or maybe they are for both. could that be possible? and for the swaybar bushings there is 3 sizes and i dont know the size i need for a 1997 xj6L.
