You broke it once. You should figure out why or else just upgrade it. Especially because with 9" of lift you may be tempted to get bigger tires at anytime.
I have some shackles that I like, but I'm not sure where to get them anymore. They have three upper holes in them, all 1.5" from each other. That gives me the option to bump the front end up or down a little depending on circumstances. So with the hardtop on and on the street with the sway bar I keep it low. With the top and swaybar off for off-roading, I can move the front end up 3/4" or 1.5". The small change in caster shouldn't be a big deal off-road. I am using them with ORD greasable shackles with 1/2" bolts.
