well, SO's tend to take better to performance parts so I'd be looking for one of those. Any years are fine, but in the 99-00 model years Cummins used a block that had a weak water-jacket casting around the driver's side firewall, about 5% of all the blocks that have it develop cracks, and not all trucks came with that block. you can tell because it has 53 cast into the block, it's called a code 53 block. I wouldn't be that worried, but just be aware of it.
look at Valair, they make a pretty good clutch, and they're not too expensive either
