GHA will be celebrating the 75th anniversary of Clarkston RFC ahead of their league encounter against Ardrossan at Braidholm.
Clarkston is one of GHAs three founding clubs and a celebration lunch will be held before Saturdays league game.
The Braidholm side will be hoping they can mark this anniversary with victory against a side who they beat 37-3 just a few weeks ago in the Cup.
GHA captain Andy Henderson believes previous meetings behind the two sides this season will count for nothing come game day.
He said: We will take confidence from the good performance last time we played Ardrossan.
But the key is to make sure there is no complacency or over confidence. We know Saturdays match starts again at zero zero.
You dont get any points having beaten them before. They obviously won the first game in the league and we won a couple of times in the cup.
We know it is a vital game for us and we will go all out to get the points.
It will be the fourth time that GHA and Ardrossan have met this season.
Ardrossan won the league meeting back in September. However GHA have won the last two clashes both in the Cup.
Despite both teams knowing each other well GHA captain Andy Henderson feels it is not an advantage for either side.
He said: Its not really an advantage to have played so often.
I suppose it changes things from the first meeting against them having not known anything about them.
From where we are concerned we are just focused on winning the game and we will be trying to go all out to get the win and the points.
GHA lie second in the league five points behind Falkirk with a game in hand and will be hoping to keep up their recent momentum.
Andy said: We are in the hunt but there is a long way to go. There are seven games to go and a lot of things can happen in that length of time.
It is up to us to try and keep winning. We know there will be some big games but all we can do is the old cliché to take each game one at a time and get the points from each game.
One good performance can install some confidence and we have managed to build on it.
I think individual players attitudes going into these games needs to be complimented because it is quite tough going into games when training has been disrupted by the weather and you dont know whether it is going to be on or off.
It is tough trying to get the mental side of it right, keeping the concentration and individual players standards up in each game.
I think we have taken confidence from our wins without getting carried away with it.
GHA v Ardrossan at Braidholm kicks off at 2pm. The Clarkston 75th Anniversary lunch takes place from 12pm to 1.45pm.
