1996 Chevy Corsica Where are the upper and lower motor moun

Shakes or Wobbles problem
1996 Chevy Corsica 6 cyl Front Wheel Drive Automatic

I have a horrible knock when I gun my engine or if I turn too quickly. I had a friend look at my car and he has worked on other Chevies however we are unsure of where the lower motor mount(s) is/are and how difficult it may be to change the lower one. Any help available is much appreciated.
