You twit.
You use springs to suit the struts.
If you're using XT130 struts, you use XT130 springs and top hats with AE71 upper strut mounts (to suit the vehicle), obviously.
You may have issues with the spring seat being too large on an XT130 strut. This affects the KE10/20/30/55 owners performing this conversion. You MAY be alright.
