Don't worry, we can assist. Most Fiberlux windows like yours use Series 350 side load balances. It appears you need the S350-25 balance. Please compare the attachmentst to be sure. The spring weight, 24B, will be the same as our 2420. If you need sash guides, check out the 18-073. If your old guides are in good shape, you can re-use them, but I just wanted to throw that part number out for you.
