This morning I placed my order with Jim's Battery. I was asked what model, year, and engine. After stating 1971 Barracuda 318 with AC, I was told that it would be a Group 24 yellow cap battery. I replied that all the documentation that I have seen states green. She (Alice) said her docs state yellow and offered either option. It will be 3-4 weeks before it will be built and shipped, so I have time to change my mind on color. The total price including shipping was $351.00.
