Toyota Repair: How to replace motor mounts, toyota celica gt, toyota celica

Question
My daughter has a 90 Toyota Celica Gt with @ 180k
miles on it.  Still runs strong and she still loves her car.  However the motor mounts on it feel like they are worn out.  When you drop it in gear it feels like the motor is ready to fall out.  
How do i go about changing the mounts.  Chilton manual wasn' very clear at all on this problem.  
Thank,
Rick

ps
no rush on this response, that car won't be back home till spring break

Answer
There are two mounts that normally wear and cause problems, you don't need to replace all of them, replace the mount on the side of the engine near the radiator and the link on the right front fender, it looks like a dog bone and we refer to it as just that, get the parts from the toyota dealer, this is a very common problem.
