thanks Jim, if I hadn't already commited to this windsor build I'm doing I'd be rebuilding this one. I am willing to do some parts swapping w/ people, but am running low on what I need.
Through a bunch of research I have found the mexicans in various forms, not all have the hecho in mexico, but some have an m denotation. This one has 7M9 on block, but am still not willing to claim it is or isn't.
