Cambridge United and Gateshead, managed by Northampton-born Gary Mills, meet at Wembley on Sunday with the winner joining the League Two ranks for next season.
Whoever wins will be locking horns again with Northampton Town after a lengthy absence. The Cobblers and the U's last met in February 2005 while Gateshead, in their previous guise, were opponents in the season they left the Football League, 1959/60.
