I was going over the BOM for the McWire and noticed that McMaster no longer carries the 4" spring specified. See below. They suggest a replacement that is weaker at 1.22Lbs/IN. Does this make difference? Or should I look for a closer match to the original at ~5Lbs/IN? 9654K167 Steel Extension Spring Zinc-Plated, 4" Length, 1/4" OD, .032" Wire This item is no longer available.
