Still pulling to left after alignment

Well, there's a glaring reason why it will pull to the left. It has almost ONE DEGREE LESS caster on the left. You can TRY crossing the two front tires to rule out a radial tire pull, but I bet that's not it. The caster is certainly what's doing it.
I'm only seeing .6 difference. Just right for the crown of the road though i prefer to us camber for the crown of the road.
