Does anyone have full parts diagrams for the different forks used by the FZS600 over the years, or can shed some light on exactly what changed and what is interchangable between them?
I bought some cheap "2002" forks to test my bike after crashing it and severely bending the forks a month or so ago. Unlike the ones that came on my (2003) bike, they have a simple cap at the top rather than preload adjusters, but everything I've found suggests preload adjusters were added in the 2000 model.
The outside spec of the forks non-pre load to preload there's no change, it's all internal. The preload version, the spring and the preload spacer or collar are shorter and the oil capacity/height is less. When you sit and work it all out, the later preload version gives you almost nothing at it's highest setting, in other words a waste of time a really just a gamic! You can transfer all the internals over from one to the other, your better off adding the earlier spacer to the later preload forks at least you get more preload, but you need to ensure this will match your riding style (pillion) or weight so as not to become coil bound on max braking or hitting big bumps etc.

When you say a few mm do you mean 1-2mm? With the correct spacers in the clearance should be just enough to get them in and out, so 0.5mm at most either side. If the fork isn't binding you should be ok, but check to ensure the yokes aren't slightly twisted.
