Engine out, What color to paint engine bay on a yellow car...

The driveshaft is not bolted to the transmission, it will just slide out. I would drain the tranny first, or you're going to have a lot of tranny fluid all over the floor when you pull the motor. To keep any remaining fluid from dripping all over the floor, i used the rubber ball from a turkey baster (yes, a turkey baster) and jammed it in the end of the tranny. Worked really well, actually.

I would drop the tranny crossmember as well as unbolting the tranny mount. One less thing to get in the way.

I would get the Stang up off its 4 wheels. Jack the car up by the k-member in front, and the diferential in back. Put a block of wood between the jack and differential to spread out the load. Place jack stands under the four jack points. I jack the car up high enough so I can crawl under it comfortably.

When you drop the crossmember, the tranny will drop until the back of the engine hits the firewall or the tail of the tranny hits the ground. I solve this by putting a floor jack on the tranny right next to the tranny mount. This supports the tranny enough so the end doesn't hit the ground. When you're ready to pull the engine/tranny, lower this jack about halfway down. If the jack is lined up right, it should roll forward with the tranny as you pull it all out.

Granted, I've never pulled an engine without friends to help out. One usually watches the jack as another lifts and pulls the engine. As you're lifting the engine, keep checking that you've unhooked everything. I forgot the engine ground strap once (had to replace it) and the fuel lines another (lowered the engine a bit to disconnect 'em). When you have a LOT of things to do, it's easy to miss something. Take it a bit slow and you'll get it done.
