Darlington's top-of-the-table clash at Spennymoor Town tomorrow evening is now sold out after all 2,400 tickets were snapped up.
Quakers lead Division One by 15 points, but Town have seven games in hand.
Both teams have said they want promotion to the Evo-Stik League, but there is only one promotion place available.
Northern League chairman Mike Amos says tomorrow's fixture brings back memories of huge attendances of the 1950s.
"A 2,000-plus gate is unprecedented in the recent history of the Northern League, though quite common in the former glory days of the 1950s," he said.
"Friday's game promises to have everything. Both clubs have had marked success, a high-profile and enjoy an enthusiastic and vociferous following.
"It's going to be like one of those derby days in the 1950s - an occasion to be greatly relished."
With turnstiles open from 6pm, supporters are strongly advised to arrive at the Brewery Field for the 7.45pm kick-off.
Moors general manager Steve Lawson said: "There is segregation in place and spectators must enter the ground where stipulated on their ticket - Wood Vue for Spennymoor fans and Tees Crescent for Darlington fans.
"Extra parking provisions have been made, but it is still limited and everyone is encouraged to use public transport, taxis and group up as much as possible.
"We'd ask all fans to respect the surrounding areas and show consideration to neighbouring residents."
Meanwhile, Darlington will train this evening at Durham City after last night's session was cancelled due to the weather.
