The correct rear mounting stud is mounted on the bottom cover for Barracuda. You should be able to swap that cover from a donor to mount that radio. If you need to be "correct", you will need to find a new radio. Good luck.
I am not too concerned with being absolutely correct as, except for the missing Plymouth ID on the face, the radio looks fine in my dash. I do want it to be securely mounted at the back. A swap for the correct bottom cover would work for me.
Thanks for the replies.
