The bolts used for the tray under the bumper are the same as the bolts used on the top ebge of the bumper (under the grill trims). They are special large head bolts and may be easier to get straight from Alfa.
The rear two bolts are just std M8 bolts, about 40mm long I think, with large dia washers.
