Balance and Shoe for Unknown Builder Grade Tilt Sash

Hello!
I bought a house built in 2002 that has all original windows. I'm not sure of the manufacturer or anything, but I have attached everything I have found since the problem occurred. I closed the window and heard a loud crack and pop noise. The balance was at the top of the tracking the plastic pivot shoe had broken into pieces. I'm unable to remove it, but I was able to remove the balance and retrieve a manufacturer tag stuck in the track. The metal measures 28" x 1/2" and reads "27 5 LU CMC 6"

I am the home owner, a quick learner, and pretty handy person, but replacing an entire window is beyond my skill set. I hope you can help!

Thank you,
Dan
