Hi Kyle,
I can understand your wanting to learn more about your car...and the questions you posted, but going forward please start a new thread for the off topic details specific to your car, so we can focus here on the 2-piece nose subject.
As we discussed previously (in emails) it is VERY likely your car came with the slanted 2 piece grille.
That follows the photos you posted.
There is no data (no paperwork that is known to exist) that will state if your car, or any '67 Shelby's, had the 1 or 2-piece nose.
As Bob similarly stated, the Shelby American completion date noted in the last registry for your car does appear to suggest it did.
We can see that by comparing with other cars completed around the same time in late January 1967.
Anyone reading this, that is aware of a 2-piece nose car, that is not listed in the first post in this thread, is urged to share that info.
It will help everyone interested in them.
Thanks
