Just had a look in my 69 2+2 which is all original (at least it appears so) your panel seems to have been replaced with a roadster panel which as suggested previously has the boot release bolted in that position.
My panel has 4 indents where the studs would be positioned. The tack welds along the top edge also give it away as being repaired at some time, originally they are spot welded. Just cut the studs off and forget.
Number plates are located lower down and on the outside Steve.
Hope this helps and Merry Xmas to all.
Tony
