I pulled the engine in my 87 about a year ago when the timing gear went out of it. All I did was make sure that all electrical connetions are undone and labled. Remove decklid, remove starter, remove ACand let it hang. I also pulled the water pump and the exhaust manifold braket to make it easier to get to everything. I was actually under the car for about 45 minutes to undo the starter, exhaust, and AC. I was able to get to all my bolts and such from the top. If yours is an Auto, don't forget to take your torque converter lose. I was able to change the oil pan gasket and lower motor mount by just unbolting the front mount that has the (what I call) cradle, rasing the engine with a hoist, then moving it out of my way. I have pulled both an Auto and a manual through the top. I didn't have to do anything with axles, etc. here is a link that I found that explains it pretty good. It took me about an hour to get it out, and about the same to get it reinstalled.
