[pre-xk] Restoration of 1933 SS1 coupe

Can anyone help with a problem I have with the bonnet (hood) of my SS1.

I have had a new bonnet made using my original bonnet as a template. =
However, as the bonnet was so rusty it was impossible to find the =
position of the four chrome plated dome head bolts that prevent the tops =
of the bonnet from touching when either side is opened.

Can anyone supply the dimensions from the front and rear edges of the =
bonnet top and from the centre line of the bonnet hinge to the centres =
of the dome head bolts?
This will allow me to complete the bonnet and to progress to the =
painting stage!

Best Regards,

Barry Dixon.
