So from the underneath the head to the tip is about 7/8. So I looked at the spreadsheet and I filter by 378156-S2 and then by qty 1 since I only found one of these so far since I have no other bolts like this with this tooth washer, most are the concentric circles with the star washers. So based on that these are my options:
BATTERY TRAY-BODY@TRAY
DEFLECTOR,FR-HOOD LATCH SUPPORT BRACKET
DEFLECTOR,FR-RADIATOR SUPPORT,LH
HOOD LATCH SUPPORT BRACE-LOWER RADIATOR SUPPORT
