What is the best way to hold the Australian head light buckets in the Rover fronts?
The Australian fronts have square holes for the nylon bush’s that take the four screws.
The Rover front has smaller round holes.
Is there a special fitting that fits in these holes, or do you use a basic bolt with a Nylok nut?
What’s best?

Why not put the correct rover lights in?
Not that it matters, just screw them in.
The factory used rivits.
