Outer Limits 4x4 Board

Im building a comp truck for next years Tuff Truck it will be based on a 97 swb vitara with a 16b motor standard 5spd but a divorced sierra case running 6.4s the diffs will be after market 60 series houseings running 5.29s all to turn 40 inch comp spec treps.

So I need a new clutch the fly wheel will be machined and a new spiggot bearing fitted but do I go heavey duty or stay standard have heard there are clutch cable issues if going heavey duty clutch.

So guys please give me some info on which way to go possible part numbers and prices

Thanks
