I'm considering the same Battery after my Autozone yellow top lost charge for the nth time even after an Alternator rebuild. That is the only battery Autozone and Oreily's have listed for our cars. If I get one today I'll let you know how it fit. Have you consider any other battery options?
Is the bracket shown in your photo the original bracket just bent to hold the battery down?
I will do the install this weekend and i want to be prepared as possible.
if I need to buy a bracket I want to get it ahead of time.
Ended up getting an Autozone Platinum battery (AGM made by Optima) with the prorated warranty for my old battery at just over $100. Had to use a battery clamp under the OEM bracket to meet the height difference of about 3/4" too small. This wasn't a biggy as AZ gave a free clamp from the battery room. Did the swap at the car park and its a tight fit. Mine is a 99 Gems 4.0s and Autozone only list the Optima D31A battery for it. One of the managers gave me the 3rd degree stating that they won't warranty any other battery choices. I talked to another manager and explained the mid year switch between 99 4.0s and 98 4.0se; then we picked up this from the list for the 98 4.0SE and went from there.
