How hard is it to change the motor mounts on a 1998 mercury sable?

I have the tools to do it. Is it worth it to do it myself or should i just take it to a shop? Thanks.How hard is it to change the motor mounts on a 1998 mercury sable?
It's simple really. Looking at the car you should have two motor mounts on the side of the motor. In order to changes these mounts the easy way is to take a 2by4 on edge or something that can hold weight and wrap a change around the brace and useing a bolt from the motor tightin the chain so the weight from the motor does not allow it to move too much where youcant get the bolts lined back up. Once you have the chain on just unbolt the motor mounts with the chain the motor should not move and the new mount will slide in, push the bolt through and tightin up repeat on both sides..
