Victory for Ally McCoist's side at home to Stirling Albion in an early kick-off on Saturday would put them on the brink of Irn-Bru Third Division glory, with a draw or defeat for the Spiders later in the afternoon at Annan then confirming their status as champions.
With a 20-point advantage over Gardner Speirs' side, it is a matter of when, not if, the Gers finally get their hands on the trophy.
They are set to return to Hampden for a derby clash on April 7 and Spiders defender Gallacher is keen to keep the Light Blues waiting.
He said: "The target for us at the start of the season was to finish as high up the league as we could and get into the play-offs.
"We wanted to win the league but that isn't going to happen.
"We need to keep pushing and hopefully we can win a few more games before the end of the season.
"We want to win every game and we want to keep the league going for as long as possible.
"Ideally we would keep it going until we face them in a couple of weeks time.
"We can only do our jobs and that is to win our games and not worry about what Rangers are doing.
"If we win and that stops Rangers winning the league this weekend then so be it. It is an incentive to keep it going for as long as we can.
"We want to play in big games and in front of big crowds.
"We have played them twice at Ibrox and at Hampden already and they have been brilliant occasions for us.
"If they had a chance to win the league, I am sure there would be an even bigger crowd at Hampden and it would be some experience for myself and the boys.
"It is an incentive for us to keep winning but, regardless of what Rangers are doing, we need to win the games for our own season."
