I agree, your pivot shoe appears similar to our 15-175. For the coil springs, see our S152-5. The manufacturer now makes the springs with the same length tongue, which does make it a little difficult in doubling them up. I'm afraid we don't have those exact covers, but we do have the 15-143, 15-144 and 15-145, which are used on the hardware we've already gone over. I think they will work for you.

That is a little weird. If your sash is 25 pounds, I don't know why the manufacturer would use four 5 pound springs. Did you find that your sash always felt heavy before? If so, you could use one 5 pound spring and one 6 pound spring on each side. I don't think you should go any higher, or your sash will be hard to close due to all the spring tension.
