2007 Yaris Battery: 26 or 35?

[Thirty-Nine]

Swapping batteries. I got a 26. When the brought it out, I said it looked a bit small. They double-checked, and sure enough it said 26 (when I check online 90% of the places recommend a 26 series battery).

However, when I got it home, it's too short as many others have said on other threads. But then I read that some 35 series batteries are too big (Walmart, for example).

So I could make some spacers to get the 26 to fit or I suppose I could see if the 35 would fit.

Did Toyota change battery sizes at some point? My battery brackets are way too tall for this 26.
