No- they won't work. If you want drive flanges, you need the ones off of a FJ80 Landcruiser. The IFS minitruck/4Runner flanges are 27 spline, the Solid axle minitruck/FJ80 flanges are 30 spline... (I think the spline counts are right...either way, FJ80 flanges are the only ones that'll work on the straight axle trucks)
