Adjusting T & T Y - link for caster and pinion angle?

Do I use the smaller upper arms that connect to the long BIG arms for my pinion angle and then the longer ones that bolt to the belly/skid pan for my caster? Or is there a jugle between the 2 adjustmants to get it right?
Thanx in advanced-I would've called TNT first but hey,it IS sunday ---right?:sad1:
OH by the way my XJ is lifted around 9" or so

Adjusting your pinion angle is going to directly affect your caster angle FYI. If you want a better pinion angle you're going to have a worse caster angle.

As CrazyJim said, adjusting one affects the other.

As for your question, you use the short arms to rotate the axle. But at 9" you are not going to be anywhere close to good angles for unless you cut and rotate your inner C's on your axle.
