Fiberglass hood- Can I use/rely on stock latch?

I have a '69 Dart with a fiberglass Hemi style hood that is set up on hinges in the rear. I need to know if I can use the stock latch up front or do I need to go with pins up there? The problem seems to be that there is no secure way to fasten the latch and the loop to the hood. The hood looks to be molded correctly for the set up, but I dont see any indication of a solid backing plate in the glass to fasten the bolts through like there is at the hinge locations. Is that just the way it is with fiberglass, pins required?
I wouldn't mind using pins, but I would prefer the locking,(keyed), cam style. I prefer both the look and the added locking feature. However, the manufacturers of the cam style ones I have found indicate they are to be used only in conjunction with stock hood latches. Is it because there isn't enough surface contact on those to guarantee, without the stock latch secured, they wont pull through the hood?
Ideally I would use just the stock latches. If pins are required my preference would be to combo the stock latches and locking style pins WITHOUT the scuff plates. I would like to avoid having 2" to 3" chrome circles on my hood. Then again, worst case scenario, they could be painted to match the hood.
Here are a few picks and a link. Not sure how much they will help. Suggestions, options? Appreciate any input. Thanks!
