Montrose face the first of two massive games when they travel to Dudgeon Park to play Highland League champions Brora Rangers on Saturday.
The second leg of the play-off goes ahead at Links Park next weekend, with Paul Hegarty's side desperate to retain their SPFL status after finishing bottom of League 2 in 2014/15.
Davie Kirkwood's team overcame Lowland League winners Edinburgh City on penalties after both legs of the play-off ended 1-1 and the stage is now set for two crucial contests.
Montrose head for the Highlands on the back of a 4-3 defeat at Annan last weekend but lost only one of their four League 2 games during April.
