Drawer

Hi I bought an old wood dresser that has no drawer slides in the middle at all, old broke wood ones on the side and a little metal piece that sticks up on the sides? I'm wanting to add actual drawer glides and was watching a girl on utube that was showing different drawer glides and recommended your company, she showed some drawer slides that you could cut to size. I think that's what I'm needing. I'm obviously new to this so any suggestions would be appreciated. The dresser is smaller in size but has 4 old dovetail drawers. Thank you for any information as to what I need would be greatly appreciated
