Product review (5 stars): Good so far, but...
I'll update review as repeated use will determine durability. My original part lasted over 10 yrs, I'll be happy with at least half of that.

The reason I wanted to put this up so soon, is to clarify something: the clutch comes with the blue spring factory installed. There is a green spring included if needed for your application. The instructions say to refer to the chart (really just four line drawings) of different washer types and a description. It also tells you which spring to use for each of these unit types: the blue one, or the black one. Yes, it says blue or black, even though it comes with a blue and green (there is no black spring option).
