Adjustable track control arm help please

[rashers]

Just fitting these to my car , is there a basic measurement to temp set these two ,have fitted them and the angle of the ball joint going into the bottom of the hub seems really tight ,would measuring the inner and outer bush centres on the old arms give a good enough starting point .........Cheers Rashers

Yes just set it to std for now
Then when it's on the car and settled you can get it set up properly
