I did manage to find a 24 hole front rim for mine but it took a while. I got my SPOX set off e-bay for super cheap because the rims were toast (the rear one) then I upgraded to Bontrager ceramic rims. Let me look this weekend in my storage, I think I have the 24 hole original front rim which wasn't destroyed like the rear one (used but still useable).
Let me know if you're interested. Those wheels got a bad rep back in the day because they used shitty Chinese bearings that would constantly crap out, and they were/are a pain in the behind to true/work on. Once dialed in and sorted out with new quality bearings, they're actually decent, light wheels (I tuned my rear wheel with an XTR m950 Ti axle and free-hub, now they're as light as a set of Crossmax).
