Not sure exactly where the front weatherstrips should go. Here's a picture of the underside of my bonnet:

I believe the 3 holes are for a retaining strip that holds the rubber in position? In that case, the rubber must be something like a blade, since it has to bridge quite a gap if it is to rest against the cross member near the top of the radiator?
In the meantime, you can see my non-original 'fix' at the far left of the picture -- a 'suitable' spring that pops the bonnet open very nicely when the catch is released.
