Thanks for all the comments guys.
Paul Here's a few pictures of the bonnet brackets i made, they may be of no use to you as all the parts i have are bespoke.

Two taper pads were welded on to the front chassis rail to bring both bracket pivot bores in line with each other, if they were not in line then the bonnet would not pivot correctly if that makes sense, this pictures shows one bracket in place with the taper pad between the bracket and chassis rail.

Made a frame out of 20mm steel tube to sit inside the oval nose profile and bonded in place, two hinge brackets were welded to the tube frame before bonding in place. Second image is of the parts i made.
Hope these help in some way Paul, see you all soon.
