Don't have that one ...
Anyway ... converting from 3.5e monster style to 3.0e monster style is very easy. The only thing you really need to convert are the number of skill points at feats (and honestly, you really don't even *need* to convert that ... the discrepancy in skill points and feats can be easily made into "racial skill bonuses" and "bonus feats" by DM fiat).
Post here the monster's Hit Dice, skills, feats, and ability scores. I will provide you with the 3.0 versions.
