Window Sash Guide replacement

A quick learner from Yorba Linda, CA says:
I just ordered two sets of 34" Series 350 Channel Balances last week and as I was replacing the balances I noticed significant wear and tear as well as damage to one of the sash guides. What would be my best bet to replace these aluminum guides? I included dimensions as best as I could. Thank you for your help.

Our 18-012 may be what you want. Even though it's shorter, the critical dimensions match, so it could still work for you. See what you think!
