I am in the process of installing the front control arms that come with this kit. The directions are a little sketchy, and the pictures were faxed so they are mostly black. Do I have to drill out holes in the front axle in order to mount the bracket that holds the new upper arm? I would like to simply bolt it on, but if I have to drill a hole I want to know ahead of time. Anyone who has done this lift please chime in, let me know of any holes, cutting, or grinding that will need to be addressed. Bolts are no problem, cutting and drilling is a pain.
