Rebuild kit attempts to cover many different Models, making it a chore to figure out exactly what parts & the order you need them in.
The manual becomes critical, but it's design is quite cryptic. If you have worked on your Crank Brothers pedals before & you review the DWG's carefully it makes enough sense for a good result.
The Long Spindles work great if like myself you need some heal clearance because of turn-out. I like them, much better for my fit needs.
