My new motor and tranny mounts came in the mail yesterday so I'm going to replace them tomorrow. Are there any potential pitfalls I should watch out for?

 

The plan right now is:

 

1. Jack up the car & put it on jack stands

2. Get underneath and loosen the bolts.

3. Lift the engine with the jack enough to get the mounts out

4. R&R mounts

 

Any tips, tricks, or other info a newbie should know?

Or maybe someone could at least verify that I'm not likely to break anything doing this? :-)

Might want to take off the pitch stopper before you lift the engine so you don't risk damaging it.

Good call. How can you tell if the pitch stopper has gone bad? Are the holes for the bolts worn too big, or what? It was suggested that I inspect that and replace if necessary. I've got a new one to install if I need it, but I don't want to replace it if I don't need to.
