The former Doonhamers striker lifted the Second Division title and Ramsdens Cup with Allan Johnston's side last term, with his fine form winning him a move to Ibrox this summer.
The Gers head down the M74 aiming to move one step closer to cup glory and Clark knows it will be a stern test against Jim McIntyre's men this evening. He said: I've had a bit of stick from the Queen of the South boys.
"They're really looking forward to the game and saying they're going to beat us but we'll see what happens on the night.
"They've lost a couple of boys from last year.
"I'm still in touch with a good few of them and they've done well.
"They had a great win against St Mirren in the cup. I'm sure they'll come into this in the right frame of mind.
"None of us will go into any game taking the opposition lightly and this will be no different.
"The stadium will be full and there will be a really good atmosphere. It will be tough but if we go in the right frame of mind and keep our heads down then I'm sure we will be okay.
"They'll have a go. They're the home team and a really good team in their own right. They'll fancy their chances and have a go."
Clark was instrumental in Queens' success last season as he topped the scoring charts in a campaign to remember for the Doonhamers.
He netted in their Ramsdens win at Ibrox and the striker has fond memories of his cup giant-killing as he attempts to avoid a shock in Light Blue tonight.
Clark said: "We knew we had a chance. It was always going to be hard going to Ibrox, as it would be for any team going there. We were confident.
"Everyone was flying as a team and we pulled it off. It had an impact on the rest of the season.
"We were confident going into the game but obviously after that win we had even more confidence.
"You'll need to ask (the manager if I caught his eye that night) but it was obviously good to go there, do well and get the goal.
"I felt as if I did well, as everyone in the team did. I scored another 40 goals other than the one at Ibrox which maybe also had something to do with it.
"That night has to be right up there in my career because no-one fancied us to go and win there but we did it."
