D^2, why would you have to change your rear end ratio? It's not 'full time' overdrive is it? I'm under the impression that all overdrives (including Gear Vendors) can be 'selected' when you want the extra legs. Yes with the gear vendors add on box, you COULD run it in OD all the time but that would defeat the purpose and you could get the same results with much less expense by changing the rear end ratio.
