One of the other clubs that I belong to for another make of car (that has 12 cylinders) features a member who makes batteries up just as you describe for those cars. If you contact me off list, I will provide you with contact information so that you can talk with him about the process. I believe that he actually puts the batteries together prior to sale, but he may be able to tell you how it is done. I am not that particular myself.
