Please take a look at the lists below.
To give you an idea, the Air Lift kit for the Land Rover 110 (part number 61724) is made up of 2 x #46132 air bags, 2 x 09115 top seat/protector and 2 x 09447 bottom seat/protector. The kit also comes with all the necessary piping, tee pieces and inflation valves. 

So, measure the inside diameter and height of your rear springs, e-mail me the dims (sales@mattsavage.com) and then I'll sort out what you need. As a rough guess, the price for most of these kits is between £70 and £80 + vat. This will come with the piping and fittings, everything you need to fit them to your vehicle.
