Update: I've got the motor and everything. i sold the cvd's for $50 on ebay and i'm going to pick up the 3.3 slidders and some screws at my lhs tomarow. i've installed the rpm stuff and the steel idler into the tranny. i made my own way of keeping the tranny in 2nd gear as well. check it out:
i used the bearrings to hold the spacing after funding out that 2 on the idler shaft and 3 on the outdrive shaft would work well.
so, i will be running a 9XL motor with 12 NmHi cells and the rcm heatsink(i've got a mod 1 pinion as well).
