Rebels, who overcame two-divisions higher and another National League South side Whitehawk on penalties last week, were awaiting their opponents with the second semi-final taking place at Culver Road last night.
It was Tommy Widdrington’s Borough side who proved too strong for division-lower Ryman Premier Division side Bognor.
Elliott Romain bagged an extra-time winner before he was sent-off as Borough won 3-2.
The final will take place on a date to be confirmed.
