I was cruising around the FS website (benefits of having a cold) and found the original installation/maintenance instructions for the FHP Jetsonic (JS2). Below is a pic of the bar from the document, as well as the "proper" aiming points for the "parked" flashers. I learned something new...I've always seen them stop pointed to the front and rear, and not 45 degree angles. I'll upload both docs to the FHP resto section.
