I can't remember off the top of my head where i got mine (I will check my files) and maybe i am not judge level scrutinizing it, but the 2 i bought for my GTOs seem to look and work great. My 2 cudas each got a mopar sealed version when i had some light resto work done by Kohr's Kustom. Dennis Kohr seemed to research and like those sealed OE look batterys. So with 4 of those kind of batterys in cars i drive "respectfully aggressive"
i have had no leaks or problems. knock on wood
