My friend just got the applied springs that already have those ends on the springs and all you need to do is punch out the pin and put the new ones on. The spring doesn't even screw into the ends. That's weird because that means that the only thing holding in the spring is the C clip. Lastly, when we put the spring in we needed to compress it a bit to get it to go in and put the C clip back on. Any thoughts on this?
