Cambridge to meet Gateshead
Delano Sam-Yorke scored twice as Cambridge beat Halifax 2-0 to overturn a first-leg deficit and set up a Conference Premier play-off final against Gateshead.
Halifax had claimed a 1-0 advantage in the first leg at The Shay but Sam-Yorke drew Cambridge level in the tie after 11 minutes before putting racing clear to fire his side ahead seven minutes before the break.
Halifax threw men forward in the closing stages at the Abbey Stadium but Cambridge held on to secure a return to Wembley, where they won the FA Trophy in March.
Their opponents in the final will be Gateshead, who beat nine-man Grimsby Town 3-1 at Gateshead International Stadium to complete a 4-2 aggregate victory.
James Marwood put the hosts ahead when his speculative long-range shot was spilled by James McKeown, and Scott Neilson's red card for the visitors shortly after half-time swung the tie further in Gateshead's favour.
Craig Disley drew Grimsby level in the game and in the tie but a second red card, shown to Sam Hatton for a second booking, left the Mariners facing an uphill battle.
They hung on until six minutes from time when Marwood curled a wonderful effort into the top corner for his second of the game before JJ O'Donnell put the seal on the win in the closing stages after being fed by Phil Turnbull.
