FC United hope to clinch promotion to the UniBond League at Ramsbottom United's tiny Riverside ground on Saturday.
The game is expected to smash the Bury side's attendance record with a capacity 1,500 virtually guaranteed.
The Rebel Reds are in confident mood after an 8-0 victory at Nelson on Wednesday which extended their lead in the North West Counties League Division One to 13 points - with two games in hand on second placed Salford City.
But Ramsbottom have proved to be no pushovers this season. They go into the game in seventh and gave FC United a shock when they met at Gigg Lane on Boxing Day, leading by two goals before going down to a 3-2 defeat.
Atherton Colls face a difficult task as they look to continue their impressive season. Fresh from a superb midweek 2-0 home victory over the favourites for second place, Curzon Ashton, Colls travel to 12th placed Silsden.
Colls' neighbours, Atherton LR, also had a confidence-boosting midweek victory, 5-1 at St Helens Town who they leapfrogged into fifth bottom.
LR hope to reproduce that kind of form at Crilly Park when they entertain sixth placed Maine Road.
In Division Two, Daisy Hill look to continue their climb out of the lower reaches when they travel to 12th placed Cheadle Town.
Daisy, who drew 1-1 at bottom side Norton United on Tuesday, are four point clear of second bottom, with two games in hand, and close enough to the three teams above them to jump over them with a couple of victories.
