Maybe the saddest M-Code Cuda you will ever come across

It was a several years ago that I last had seen it, I think it was the fastback Barracuda. All I request is a guesstimate. I do not have access to my books for production numbers. Also would you know besides the M in the VIN, is there any identifiable features I can use to confirm it is a M code from the parts?
I'll pass on this, maybe someone else will comment.
