After you get the engine mounts loose and jack the engine up and support it safely. Than you have to remove all the pan bolts and drop the pan down. Before you can get the pan out you will have to reach between the pan and engine to remove the oil pump and oil pickup. Besides the2 bolts holding the pump on there is a nut about half way back on the bottom of one of the main bearings that holds the oil pickup. It is a fairly hard job just because there is no to much room to work and you have to squeez your arm in there to get to the pump and pickup. I do not think you can get the engine high enough to remove the pan without removing the pump and pick up first. Of cose when you put it all together you must make sure you get the pump back to the block clean and tight so there is not a leak between them. this is kinda hard to do with your arm stuck in there. You can't see what your doing you have to do it by feel and the only thing I could find that would fit was a open/box end wrench. Which is not good because your spose to torke the pump onto the block but, I just couldn't get enough room to get a torke wrench in there maybe if your young and paitant you may have more luck than I did. I did this job on my 78 Zephyr maybe on your car you can get more room so that you can leave the pump on that would be the way to go if you can make it work. By the time I was through I wished I had jut taken the engine out it wouldn't have been much harder and I could have done a better job of changeing the gaskets. With the engine out I could have changed the rear main seal as well I needed it anyway. See if you can find a Mustang guy in your area he can probley tell you the secret.
