if it were me, i would remove the auxiliary belt, and store it with most of the weight off the wheels, ie, on axle stands maybe.... i wouldn;t worry too much about anything else, if you wedge the clutch pedal down, then it means the hydraulics are under constant pressure for a yr, which i woldn;lt think was good..... on return, i would then change the oil asap, coolant, probably the brake and clutch fluid.... and also get a bew cam belt fitted asap..... oh, and clearly store it with the battgery disconnected, or even removed..!
