I called them, they were my first stop. No luck.
Well that sucks. Makes it a bit harder. There may not he any pre made kits but that doesn't mean it can't he done. If the truck is independent front suspension (IFS) then you could try cranking up the torsion bars and that will give you a bit. At least an inch or two. It will definitely decrease ride quality though. Then pick up a helper spring for the rear or maybe some new springs back there or shackles to lift the hack up. If you are solid axle in the front then you could probably use almost any solid axle kit for a truck almost matching specs to yours. Check out the Suzuki Samurai. They are fairly similar to yours and may have some almost interchangeable kits. Do some research on pirate4x4.com and read up. There is plenty there I wood imagine.
Australia has lift kits for the Rocky. Down there they are called a Feroza. A Rocky in AU is a totally different vehicle. The cost is around $1500 plus shipping.
