Scam or Real? What are your opinions? LM1?

[69LM1]

Well,
I just took the plunge on this one. It required a $300 immediate down payment, which I am leary(sp) about, but the spelling looks ok. The price was not a "to good to be true", but a good deal none the less.
On further inspection of the pics, it has the chrome air cleaner dish, which means 4brl, if it is a # match 350, and has the 12bolt rear num match as well, then it may be a LM1?? I say LM1, as it has the 3 speed manual as opposed to a 4 speed, which I *think* was the only manual you could get with the SS350 option??
