Ayr progressed to the First Division play-off final with a 7-4 aggregate win over Forfar.
Michael Moffat fired home from 12 yards but Dale Hilson levelled for Forfar when he converted from close range.
Mark McLaughlin headed the hosts back in front only for Barry Sellars to level matters with a 55th-minute drive.
Forfar took the lead with a Ross Campbell penalty on 90 minutes but Alan Trouten's injury-time spot-kick ensured a draw on the day.
Forfar's penalty came after Martyn Campbell fouled Christopher Templeman while it was a foul by Stephen Tulloch on Trouten that led to Ayr's leveller.
