Need help with my G3-build

[suicideneil]

Both the pro and normal ratio diffs will fit any given HB truggy or buggy, but the specific ones Mike sells are for the Lightning- buggy ratio ones and pro truggy ratio ones, so our man would want the ones listed as buggy ones. HB also sell hardened and standard (non-hardened), but I dont believe that effects the ratios as such (mine are hardended buggy diffs in my maxx).
