I can't trust my eyes to set toe anymore? Okay, eye, but it's usually pretty accurate, except when I'm seeing double.

Funny story, I once set up the alignment on my real car with a piece of string and a ruler in a truck stop parking lot.

EDIT: Did a little test fit just now with the super shorty and the M07. With both battery holders installed backwards, it needs about 1/4" (6mm) of foam to be held in place.
