I got stranded in the Florida Keys with the family this weekend. Couldn't get a jump at the Publix. Walked 1/4 mile to the Kmart (I HATE kmart) and spent 30 min trying to search the web for what diehard fits a JK. It's an impossible job, just try it. I ended up walking out with a group 35 for $125. It sorta fits, but it's taller so I had to bend the brackets on my trail rocker to get it to fit.
This was 1 day after I ordered a new Odyssey because she was getting slow to crank. I tried to cancel the amazon order but it was too late. So now she starts with a new group 35, but I have a $312 Odessey coming in a few days. Arrrrg, I hate wasting money.
