mrsparky -

sorry for delayed reply - just lost a close relative and spending time on arrangements.

In the anime (animation version), the ying-yang sign appears on the hood (bonnet) where most hood ornaments go.  The jeep is military green.  In the original manga version (the graphic novel, samples provided at my link above) , the symbols are as depicted.

Oh, in case you guys want to make the matching Smith n Wesson, it's got a ying-yang symbol on the side.
