4 link help

[Tim's68]

I have a Auto Weld Chassis 4 link to install and need some help installing.
I understand that I need the chassis at ride height and the pinion set on the rear end. What comes next?
I think the bottom bars need to be level @ ride height? Correct? Top bars are level too??
Once installed, what is a good starting point when it comes to adjusting the 4 link ....... for the street.
Do I screw the heim links half way in @ install? Will that allow for plenty of adjustment.
Could someone post some pictures of what they have?
How much up / down travel would I have with a 4 link before they bind? I will have air bags.

Thanks for everyone's help.
