I just looked them up. 12.05 L x 6.85 W x 8.90 H. Shoud fit your okay. THey were a bit wider but sqeezed in snug in my application.
I purchased locally (Battery Depot or Battery outlet). They special ordered them (over night) and then I asked for a discount before I paided them and they gave mile like 10% or 12% off. So I was a happy camper.
