Convert stats from Sidewinder: Branded for Recoiled to GURPS?
 

Does anyone know of a chart/formula for converting d20 stats from Sidewinder: Branded for Recoiled to GURPS? I am reading through the Fort Griffin source material, and would like to run a campaign with my group using GURPs rules. I could manually regenerate all the NPCs, but thought someone might have already done some of the legwork on this.
