TRL, What I did was to take the "F- block" and match it with what ever rear block that lined up both sets of holes so they were parallel. (sp-?) I know Josh is always trying different stuff with his car. Josh did mention that he used a R+3-0 block.
Try it and see how it lines up.
As for the Losi hubs, if you install it the way they suggest, you will get the added toe in. If you mount them backwards, they take out that amount. The holes are drilled at an angle.
Hope this helps.
