any detailed pics/instructions on the amount of cutting required?
The orange lines are the cut lines. Here are some reference points:
where the yellow circle is, on the top of the rail, there is a square with a nutsert in it. That nutsert is used for the lower IC mounting bracket. you cut just in front of it.
you come straight down, then follow that angle.
Run the cut lines with masking tape, so you can find an index point on both sides to make it match.
Then cut straight across the bottom.
Where the red circle is, you'll trim the "ear" off of the body mount and grind is flush with the frame rail.
As an fyi, if you are running remote resi coilovers, you will probably have to grind down the resi front mounting bracket so you can still bolt it on. ( because there is now an additional thick piece of metal between the nutsert hole and the framerail.
I'm sure SVC has more pervasive instructions out by now, I'd just call them if you need a step by step.
