i would send it in for warantee if i was keeping them and it hendered the ability for the mount to perform but since it affects it in no way other than cosmetically i never did anything with it. now im upgrading to solid mounts....as in no urethane..a solid billet chunk of aluminum thats why im selling these. not becuase of this minor damage. in fact if i wanted to keep them i would run them just like they are..they have been in 3 cars like that and it didnt affect the performance at all. the motor is in there just as stiff as the day i got them.
