It is easiest to do this without the springs installed for lining it all up but it is not necessary. Line up the bracket up along the seam, you want to drill your holes so you leave enough meat on the bottom of the hole but still have enough room for the nut and washer on the back side. Also make sure that the stop will not hit the brake line when the suspension is at full compression. I have more to go here but I hope with the pictures and this description will help enough to get going.
