Ok, I read the link and it said this is sort of new battery offered by Optima, I doubt this is true - ebay advertisers are so ghey. Anyways, I went outside to my 86 and here is the dimensions, respectfully -
Length : 9 3/4"
Width : 6 1/2"
Height : 7 1/2"
(all rough numbers, but close, I was shivering outside)
So it looks like this battery will fit a C4 just as well as a C5. But since Yellohh is a C6 owner, it doesnt really matter what I say, and its pointless to suggest a cheaper place to purchase it from either. But for what its worth, buying it off of ebay is problematic on batteries.. Its way harder to mess with RMA's over the internet than with your local yocal Vatozone or O'riley.
