Jivin, I was just on the Stew-Mac site the other day and they have a beautiful detailed drawing of both versions of the TonePros TOM's. Just navigate to the TonePros TuneOmatic bridge section. It gives you the string spread, saddle arc, post centers and all that and under the SPECS tab they have the great drawing with dimensions. Check here: Stew-Mac TonePros
Hope this helps.
