I just had my vehicle at the dealership last week for it's final free oil change. They told me my battery was only producing 220 CCA (factory new is 440). Decided to just go with the best and get the Optima. The Optima is a shorter battery, therefor the J hooks for the battery tie down are too long now. Has anyone been in this situation? What would you recommend for bushings so I can get the tie down snug with the wing nuts?
