Help! Heim Adjustments

So I bought some used Icon Billet UCA from a member and need help setting them up.

Where to begin where to begin.

They're not on the truck yet and really I'm looking for maybe a thread count or measurement to set the front at before going to firestone for them to adjust the bottoms.

Icons instructions said they come set to most common set up, but these have obviously been adjusted.

Just here to learn. Thanks

 

I'm pretty sure you'll get a better result if you put them on before you take it to adjust the lower pivots. Just have them align the whole thing

 

I guess I may have to, I don't know how much experience firestone places have with heims is why I thought I should ask first.

Your advise is probably what I'll do unless someone can take measurements for me. Thanks
