motor mounts

I have a 1998 mustang gt and i think i have a broke or worn motor mount. A couple of buddies and i are going to tackle this problem. I just need to know if i should use a hoist to life the engine or should i jack the engine up by using a piece of wood between the jack and the oil pan. And also does anyone have any idea of how long this task will take?

It's not especially hard, maybe plan on an hour if you've never done this. Only problem is trying to reach them. But you can get away with using a jack.

Also get mounts for a convertible... They're a little stiffer but are directly interchangeable.
