Stranraer secured their SPFL status after a dramatic 3-1 Pyramid play-off victory over East Kilbride.
The tie was evenly poised after a 2-2 draw at K-Park in last Saturday's first leg.
Grant Gallagher volleyed in the opening goal for the hosts and it looked like being enough until Keir Samson equalised for the Lowland League champions.
Both sides had chances in extra time but it was the Blues who struck through Craig Ross in the 117th minute.
Stranraer made the game safe with an Aiden Gilmartin goal in the 120th minute with Lewis Spence sent off for East Kilbride in the final moments.
