318 msd 6al, msd blaster ss coil, msd distributor not working

They are a couple degrees off from one another, when I drop it in I still just use the rotor to guide where #1 goes correct?

If the rotor is in line with the tang or at least close to it then yes, you can line it up that way.

More often than not, the rotor and the tang don't line up. And that can throw guys off.
