Sir/Ma'am:
I'm trying to purchase and replace two window non-tilt balances and I just needed a bit of help ID'ing some parts and confirming what I need. The balances themselves measure 27" for the metal and are marked 2630, looking at them I am fairly certain that I need either S380 or S385 to replace them. I measured the bottom shoe, as that appears to be the only difference, to confirm its depth and I got 1.075" with calipers, which is more than 1" but less than 1 3/32" which would be 1.09375. I'm assuming that is likely wear and tear as this window is nearly thirty years old and that I should go with the deeper shoe?
The other question I had is that there is a small piece of sheet metal that is held to the bottom of the sash with a screw and seems to play some role in retaining the balance, however I am missing one and I'm having difficulty ID'ing the part and procuring it. If I can't find it, I'll see if I can fabricate a suitable alternative, but I'd rather have the right part. Unfortunately, I'm having issues with uploading photos so I've hosted them on another website instead, the links are below.
