After rebuilding the HV battery in my car I seem to have misplaced the 12mm bolts that hold down the battery assembly to the sides of the body. When I go to the hardware store how do I make sure I buy bolts that fit?
Maybe Ericbecky (EV Powers | Hybrid Battery Service & Repair. Prius Insight Civic. 56 Corry St, Madison, WI) or Matt (Texas Prius Battery Replacement) has spares they can sell you?
If you have another bolt like it take it to the hardware store. If you don't have one the right length find another one that threads into the hole and estimate the length in millimeters.
