OK...see if this helps. Freidman's book Shelby Cobra at page 98 shows a shot of No. 1 with Morton at the wheel. It's from the side, but you can see the right hand side front scoop over the grill (ie., it's the 427 proto.). Looks like a square tailight out back.

Then I go to pages 102-103 and look at the Gurney/Johnson No. 11, which looks to have the identical front bumper/light treatment as No. 1 (not too surprizing given them both being team cars). Page 102 has a side-rear shot of No. 11, and you can clearly see the number plate light (no plate, of course), and less clearly the boot handle.

I think one might fairly assume No 1 had the same fitment out back.
