The timing configuration on the lemans is on the V shaped grooves that are on the housing on the engine side and on the sprokets themselves. line them up exactly and it should be fine, I found that looking downward onto the housing while turning the sproket works best, by the way the water pump tends to move the belt when you are setting it back into place so compensate by moving the sproket in the opposite direction.
