thats funny cause the same exact thing happened to me a while back while installing these on my accord....DO NOT USE AN AIR GUN FOR THE TOP BOLT!!!!!! thats why it happened. mine were brand new ( i wouldnt blame this guy u get them from) and i got them from jcwhitney and they sent me a new one right away. you can order a new one individually for like 80-90$ shipped from coximport or jcwhitney.. sorry to hear but think of it as a learning experience as i did.
