Indy,
I see it is your first post. Welcome to one of the greatest clubs in the world.
I think if you will go to NAPA and get two Mustang GT mounts #6021637 you will find these will work just fine. (use these for both left and right)
You will be able to mount the AC and Pwr. Steering pump if you want, but you had better be good at making your own brackets!
I'm sure you will be back with more questions, which we all look forward to. Do not hesitate to ask for help! You have come to the right place.

Ps.. we're 2 hrs & 50 minutes from you (east) and right off of I-70.
