Can anyone give me a clue how the above goes together / works please?

I stripped the car about 4 years ago (I know...) and boxed everything.
I even took pictures of most things - but not the underside of the slam
panel.

I rebuilt the front end - and on fitting the bonnet release mech I
can't figure how it goes together.

I don't remember an internal bonnet release by cable - but there may
have been - and if there was its not where I put it :-)

There doesn't appear to be (or have been) a lever suitable for poking
through where the grill will go.

The assembly which is the body of the release mechanism hangs down
anout 1 1/4" in front and behind so it isn't obvious how the mechanism
can be shifted to release the bonnet

The nice people at Mini Sport thought that late Clubby Estates had
internal cables but weren't sure

Does anyone have any ideas or better still pictures please?

Thanks in anticipation.

Cheers

Pedro
