All you need to do to flip the mount around is press out the bolts (they are press fit in) then flip the mount upside down and sucure it with some new bolts/nuts.
Its something you can get done in 1-2 hours.
The calmini struts arent any longer than the stock ones.
They seem to be alright. They are air charged, not gas.
People tell me that gas charged shocks arent even that great for 4x4ing. Cuz its too hard to fully compress a gas charged strut, so your front end wont flex to its full capability.
