Take a look at pages 6 and 7 for information on setting up the locstions of the upper and lower mounts.
https://static.summitracing.com/global/images/instructions/hli-19553.pdfThe critical thing you will see is that both control arms should be parallel to the ground at the same time. As you go up and down from center the camber will change, so you do want to check it when the lower arm is level.
I will add a caveat that the geometry should be the same for any proper MII installation assumes stock length control arms and spindles.
The greatest majority of parts you can buy are the stock lengths, but if you find that things don't line up reasonably be aware.
