Hi Norman,
I am obviously doing something wrong.
Here is the text to go with the pictures.
The top screw is countersunk.
The bottom hole in the grille bolts to the flitch.
The curved bracket is also the latch for the front bonnet catch.
NB if your radiator is original UK, the captive bolts will be BSF
Part numbers are: offset bracket – 329607 for 7 and 11L; 329608 for 11
Curved bracket 298305 although I don’t think they will help much.
There must be some brackets out there – perhaps a request in the parts wanted would get you some. You could try John Gillard.
If all else fails, they would not be difficult to make.
I hope this helps.
