I don't think theres a guide.
What I did was jack and support the car by the subframe (far enough away from control arm to ensure you had room for major tools and a good fight. High enough so you can drill from below, the rest of the suspension will be in the way from the top.
Remove the cotter pin and balljoint nut. Then split the balljoint from the knuckle if you are using the pry down and hit method (oohhh you know this is detailed in the axle swap thread) if you have a pickle fork you can split the joint later.
Use the new bolts (in the new joints) as a guide for the ending size drill bit you need. Punch the center of the rivet and start drilling. Once the rivets are gone, pull it out and bolt the new one in place. Reassemble the joint to knuckle, nut and cotter pin.
What most find when they grind is that pulling the heads off the rivets doesn't help. GM put them in hot enough that the entire rivet needs to be removed before they'll come off the control arm. Drilling is the quickest/best way that I've come across.
