Step 1 - Get it inspected by a good mechanic who works on 4wds.
Step 2 - Wait and see what the mechanic reports on.
Any probs with the motor / gearbox / transfer case and your up for big $$$.
Already as mentioned you will need the handbrake looked at and a new set of tyres to match the lift. A full service replacing ALL fluids and filters are on the cards especially the radiator then you also can't forget the brakes.
Good thing on it is the rear bar already and the lift kit as long as the suspension isn't flogged.
Good luck mate as if the Cruiser comes out alright once inspected they are a great machine.
