Those smaller batteries can tuck in some of the tighter areas. I didn't think about putting it closer to the starter.

Dyno - Can you fill that crack with some melted plastic? If you can, I would drill a hole on the ends of the crack so it won't keep cracking, then try to fill that and the crack with some hot black plastic. Looks like a ton of nastiness in that old battery of yours!

What is everyone doing with the old acid and lead plates from the batteries you cut open?
