To change the mounts you have to take the strut out, while its out best to change the top bearing aswel. Removing the whole strut is fairly straight forward, you can use a lowering guide for tips.
However if you mean the very top bit you see in the engine bay, there not much point changing just that. Not sure what you mean fitting the v6 items?? Yozza sell the washers which is just a case of unding the top nut with a swan neck spanner/hex key and dropping the washer in place then do the nut back up.
