I've maintained this spreadsheet for Group 48/H6/L3 and 94r/H7/L4 for a few years now, mainly for GM trucks and SUV's but there are tons of vehicles that use both. If you can use it, great.
Prices and suppliers change all the time, so keep that in mind. Your "Acdelco" battery might be straight up Clarios or Delkor but don't be fooled cause Clarios owns Delkor as well as a half dozen other brands. If you took any random vehicle off the street and traced its batt back to where it was made, chances are it's a Clarios-run plant.
If you see anything with Duracell on it, that's East-Penn since Proctor&Gamble signed a contract with them. These are sold at Sam's and Batteries Plus.
As far as Amazon goes, they're only going to sell AGM's due to their shipping policy. More and more come out of China but there are still a few Clairos, EP, Enersys, etc on there (usually way more $$$ at this point).
