Remove the fuse block (10 inch socket) for 3 bolts, a 12 or 13 inch socket for the positive and negative cable to the fuse block, remove the coolant reservoir bolts ( just to slightly lift it out the way) it won’t get drained or removed. Once that is done it is fairly straight forward (on the right side). It helps to have a few misc swivel attachments for your 5/8 socket too. To me the drivers side rear was the absolute worse and had me cussing up a storm. I only removed the hose deal that plugs into the brake booster and unplugged the electrical thingy that plugs in there to give me more room. I left the valve covers on and had that side done fairly quickly. It might help too to jack up the front left of the car. Took me all of 3.5 to 4 hours to complete.
