I am guessing its a mount for the new version 5.0 flux capacitor.
or prolly a energizer bunny.
I'll be bringing a friend in tow. Sunday looks to be the nicest day of the week.
And the winner is: Flux Capacitor:thumbup:
It is a battery drop out box mount. I need all the bolts cause that yellow top Optima is heavy.
Hope to see you guys at the XXX this Sunday.
