I'd say 6 possibly 7 because I sort of did a similar thing. I had an extra set of disc brakes /hubs that I rebuilt out of the car (calipers, bearings etc) and swapped them in. Your supposed to tighten the link bolts up with the car at ride height. Since the car is pretty low, i jacked the car up and put the 4 wheels on some wood blocks I made. That raised the car off the ground about an extra foot so I could get under and tighten the bolts with the suspension at ride height. Of course if you have a drive on lift or a pit, it makes it 100% easier. And then after that, each hub is slightly different and my car didn't drive straight so I had to align the car. Since I did it myself with a buddy it was an extra pain. Of course you could just take it somewhere too, but I wanted to put in eccentric bolts to get a little bit more camber.
