130 Euros is crazy money for spare bodies from pedals that only cost 79 Euros new! (Xpedo Thrust NXL)
You don’t need any of that anyway.
Remove one of the springs from the existing body and you’re good to go. The axle slides out after loosening off the bolt on one end. Don’t pull it all the way out, remove the spring and then slide the axle back in and everything is much looser.
