Adjustment for positive Camber?

73 Duster with stock suspension.

I need to correct my front tires as they are currently in positive camber.

Two questions:

1. Do I turn the adjusting nut on the upper control arm clockwise or counter clockwise to correct this?
2. Do I turn the front facing or rear facing adjusting nut on the upper control arm?

Cheers
What is your intent and how much +camber do you have now? If you intend to slalom or track day with the car you probably want a heavy duty antiroll bar with about 3° negative camber and 5° caster. For a street driver your best bet is to follow factory specs.
Seems to me this is a situation to go to a good alignment shop.
