Is a '69 AMX considered a mopar A-body?

You found one? If not there is no cred here. All the manufacturers had factory built race machines. And no, a AMC is not a Mopar.
No. In fact I don't believe it's a 390. (At least that's what the guy is saying.) And I'm not looking for "Cred?" Information at this point. And options on what to do with a '69 AMX non numbers matching?

I'm willing to bet aftermarket is limited for AMC blocks. But have to start somewhere. And I thought I would throw it here in A-body forum. I also have a B and E body. But they may be even more particular to their body styles forms.
