Hello, I bought American Craftsman windows series 8500 from Home Depot in 2006. The spring broke. I cut out a space and removed the pivot shoe, I have two coil housing pivots
15-087 (going to replace both side while I'm at it). The original coil housing pivot has 8 stamped on the side. I was going to purchase 8 lb.
series 180 coil balance but see that your company recommends to buy the
15-086 pivot housing as well. The original housing only had the
15-087 pivot housing. would you recommend I buy this as well and why?
thank you, Patricia
