The young Gers are seeking a spot in the final of a competition in which they have triumphed in three out of the last four editions.
It's a much-changed - and relatively more experienced - starting lineup from the league victory over Motherwell last Thursday, with seven new faces coming into the side.
Both goalkeeper Rydnn McGuire and full-back Ashton Scally are involved with the first-team in their training camp in Spain this week and drop out of the team.
It means Alfie Halliwell, currently on loan at Albion Rovers, comes in between the posts, behind a backline of Arran Kerr, Jack Wyllie, James Reid and Lyle Wark.
In midfield, Aiden McCallion captain's the side and is joined by Calum Adamson and Aiden Crilly.
Max Cameron will lead the line in attack, where he is supported by Callum Burnside, who has scored nine times on loan at Alloa Athletic this term, and Zebedee Lawson.
Among the substitutes this evening is Sam Reid, Ben Hutton, Conor Owen, Calum Young, Cameron Fernie, Luca Rankin, Lewis Stewart and Kyle Glasgow.
Kick-off in Milngavie is 7:45pm and you can stay up to date with the action on X @RFC_Youth.
