Chassis to Bulkhead/Vertical scuttle rivets

[AdamQ]

Does anybody happen to know the size and/or a source of the two rivets that secure the upright bit of the scuttle/the vertical engine bay bulkhead to the chassis either side of the steering column?

I could obviously use a couple of nuts and bolts, but ...

Thanks ...

Mine's always had nuts and bolts. Handy when you want to remove the scuttle.
