I have the ATX20 from the first group buy and asked about the ATX30. Happy to see it will be made as well. Please place me on the list for a 91-96 ATX30.
Can you make it for the Antigravity V-10?
FYI to those that are on the list, trays are almost complete and requests will be fulfilled. Thanks for your patience and support!
Please add me to this list if possible. I’ll PM for payment and coupon code.

@MrHugo i chose the ATX 30 as my optima Redtop has 720 CCA. Plus, the additional weight over the ATX20 is negligible. And the savings in weight over my current battery is ~26lbs.
