I'm needing 2 window springs with the same end connection and the stamp on the spring says 28B BSI LH. But I don't know the part number

Hello there!
This looks like our S775-28 with a stamp option of 28B. You'll just need to measure the size of the shoe to determine if you need a 1" shoe or 1-1/4" shoe. If you have any questions just let us know!
