t bar slot horizontal? vertical?

I think the thing that matters most after the left/right thing is to make sure the LCA us completly in the far must downward position

I am getting ready to do mine and seeing it is all apart I will install the lower control arm and after I make sure it is all the way down I will install the bars then jack the control arm up to attack the rest if together.

I could be wrong but I am pretty sure that how u have read/researched it
