Look to the back side of the LH shock tower/control arm mounting point. You'll see one round hole and a slotted hole above. Hook the short end of the spring thru the slotted hole and out the round hole.

Don't want to step on any toes, but I think the hole location Scott is describing is for attaching the spring that goes to the clutch arm coming out the side of the bell housing on a manual tranny car. The emergency brake spring goes from the actuating lever hole (where it pivots on the transmission mount bracket), to the inside rear of the frame rail under the pax compartment.
