The rear line connects from the belly of the car to a T fitting on the rear axle. There's no need for two rear flex lines, as the rear wheel cylinders don't move relative to the hardlines that travel along the axle. Because the axle moves relative to the body, there's a need for a single flexible line there. The flex line and the T fitting are on the driver's side of the axle, held to the top with a single bolt. Follow the hardlines along the axle and you'll find it.

Don't forget the copper o-ring!
