You'll need to remove the console. I didn't find a guide, but it's pretty simple. I'd put the shifter in D prior to starting. You will need to take off your T- handle first (remove retaining clip and gently pull up). Then pull your ash tray out. There should be two small screws under it that come out. Then lift the rear of the console shifter plate up, and slide it towards you and out. There should be two more screws inside the console compartment and several more up near the actual shifter. Then, lift and slide the entire console out. At this point, I think all you have left are 4 bolts mounting the shifter to the tunnel and the removal of the pin from where the shift cable attaches to the shifter.
I got my car with an aftermarket shifter and have been returning it back to stock. I would have given you bolt sizes but I can't say for sure if I have the right sizes myself!! Hope this helps.
