I'm glad you asked. I have a V8. I still have the original factory battery and I've been looking around for a replacement. The Autozone and Advance websites say that I need a 24F, but I will double check when its time to actually buy one. Thanks for the heads up.You have the 6 cylinder by chance? Ive worked on quite a few, tray is sized for a 27F on v8 models and the 6 cylinder takes the 24F.
