'78 T/A WS6 ride height settings

[Griffin]

Question on setting the ride height: I understand that the lower A-arms should be level at ride height, but where on the stock arms do I need to measure? I saw that there is a raised and kind of flat area on the rear side of the A-arm...is that the place?

For now, I'm using stock A-arms. Would it be better for me to set it up using the camber settings? If so, I've read that the camber should be around 0.5 deg negative - is that correct?
