my chain blew off and took the factory case saver with it. i bought a pro design case saver to replace it. when i went to install it tonight i noticed that the top mounts for the case saver is gone. its attached to the bolt thats still in the case saver. the bottom is about the same but i can almost thread the bolts that came with the pro design into the lower mount. is there anything that i can do to get this pro design on and have confidence in it?
