Liversedge earned a crucial point in their fight against relegation from the Northern Counties East League Premier Division on Tuesday night.
Sedge opened the scoring after 15 minutes when Rob Thomas laid the ball back for Vaughan Redford to fire home.
A strong Nostell side tried to hit back but were met by solid defending from Tom Coyles, Brad Patefield, Nail Coulthard and Tom Elliott.
The midfield of Cody Cromack, Arron Rogers, Callum Brooke and Thomas also worked hard to preserve the 1-0 lead to half-time.
Kenny Tafireyi and Redford worked hard up front but Nostell grabbed an 80th minute equaliser, via a Moles penalty, to send the semi-final to extra time.
Cromack curled a cracking free-kick into the top corner to restore Liversedge’s lead after 100 minutes.
Coulthard added a third five minutes before full-time but, in a dramatic finale, Moles converted a second penalty.
Thomas guaranteed Liversedge’s cup final spot when he cut inside and rifled home to seal victory.
Harrogate Railway face AFC Emley in a delayed quarter-final, with the winners meeting Frickley in the other semi for the right to play Sedge in the final.
The Under-19s returned to league action on Monday when they recorded a 2-0 win away to Thackley.
