When I take the cabby off the road over winter, all I do is leave the handbrake off with the car in 3rd gear, leave the rear windows down very slightly to stop any condensation from building up inside and pump the tyres up a little (around 40psi mark).

Don't even disconnect the battery. All I do when getting it back out on the road is to crank the engine over with the coil lead low-tension side disconnected until I get oil pressure (and fuel as it is a carb model) and then it starts straight away.

It gets dragged out the garage, tyres pressures rechecked and used .

No need to even recharge the battery either but then mine does sit in a carpeted garage with a breathable outside car cover on it (Classic Additions one)

I have had the clutch stick to the flywheel once though, but that can happen regardless of other storage precautions.
