Dont know about the part number for the bracket
But the bolts holding the rad unit it, the ones that go through the wing, are fairly standard size and type, admittadly they will be unf nuts and bolts
I replaced mine with metric equivalent ones, if you find a local bolt and fixings trader near you they will be able to sort you out a lot cheaper than trying to source original parts, just take one of the bolts for length to them
Also allow for two washers, one either side
It helps
