I installed the 24-DLG Duralast Gold last night (10/26/2012), it fit perfectly!- No room to spare. It took all of 15 minutes and I'm very sure to have no battery issues this winter in Minnesota now that I have 750CCA!!!
After debating which battery to get, after reading all the great post, I finally decided. I got the 24-DLG from Autozone instead of the 56-DL yesterday 11/13/11.
