Mike - yup yours and mine are the same. Plus it makes sense...their both 12 bolts from LA. The subtle differences could be a prime example of what John spoke of earlier.
By any chance do you have a shot of the underside? I'll bet yours are serrated also.
Heck, for a minute I thought you had a viper head mark.
...Is the "P" in your first pic a mirror image, or is it a backwards P? I'm asking because I have several P's also...
