It looks like I need a new battery as mine is starting to die. I've read through all the posts about Optima batteries. I'm confused...Optima says the 34R is the correct battery model for our trucks yet many members are using the 75/35. Is it because it fits better and dosen't take as much modification to work/fit? Does anyone have the 34R installed in their Titan? Pictures would be appreciated. Thanks in advance.
