In most case’s when an emblem hole is filled, all you have to do is look at the back side of the panel to see where the holes were. You’ll need to look on the back side for either filler ooze! If you don’t see anything, get a bright flash lamp and hold it in the general area. You can usually see holes through the fiberglass this way. The pigment of the filler will not be the same as the original fiberglass and thus, it will show you where the original holes were.
The assembly manual will get you in the exact area too, but if you want to hit the old original holes finding them is the best way.
