I just bought a AutoCraft TX12 battery from Advance Auto Parts and it fit! It's very snug and I had to make a small extension for the + battery terminal and remove the rear ECM bolt, but it's in working great. It only has 180 CCA but I really don't run the thing unless it's over 50 degrees so I think I'll be fine. The battery came to $71.51 after a 25% discount code (which you can just about always get for Advance) plus a $5 core charge and $4 in tax. Not bad!!
