The S170-409 is the closest part I could find on your website. The photo and dimensions match perfectly, however, my springs are stamped 410 vs 409. Actually they are stamped 410 and SK underneath that number. If the 410 is not available perhaps the 409 would work. Thank you

Alternatively perhaps I could combine and S170-405 and an S171-405 to match the S170-410 rating. Obviously would need the additional parts to support the S171-405 spring. Thanks

Hello! We are not able to supply these springs with a 10 pound rating, unfortunately, bit your idea of using two 5 pound springs is a good one. I do that myself in a pinch and find that it works well.
