I came up against a problem when I attempted to swap springs over in my octavia on the weekend -

can anyone tell me what size the triple square tool is needed to undo that bottom bolt that holds the strut into the bearing carrier, and also - is that bolt re-usable or do I have to buy a new one. Finally, once undone, will the suspension drop low enough to remove the strut without needing to undo everything else like the axle etc.?

Looking for replies from people who do this all the time

PS - I have a set of triple squares but mine only goes up to M12 and its not big enough.
