Zipty used to make some billet steel mounts. They made the late model kx mounts with the spring on the inside. They also made the the stock kx500 mounts. I have one of each kind on two of my kx 500's. No more sagging pegs,and with the late model one's no more broken springs. It was a long time ago when i purchased them. May be able to still get them through his dad at terrycable.I would try and call them and see if you can still get them.
