Mudbunny jack/drill template question

[lincolnic]

On the Mudbunny drill template, I notice there are specific jacks used (I'm guessing in order to have enough space for the battery). Which jacks are these?

Would regular open frame jacks be too big to include a battery in a 1590B? Gonna build one of these for a customer and he'll want the option of battery power, so if I've got to get specific jacks I'll pick some up.
