I don't know, tape doesn't sound like a very good method to me. Maybe to temporarily install to see how they look, but then a chance of making a mess....When I installed my hood ornament on my '55 I gave it some thought for a while and decided to put it on. My holes had been welded shut by a PO. I used a Dremel tool with a pointed stone to open the holes up from the back side. If your holes are bondo'ed he may have put a backing piece behind or not. Take a look at the back and see what gives.
