Thinking again about this - we had something similar with an old caravan's rear lights many years ago. The lens was held on by a straight (not pointed) threaded screw which screwed into a small brass nut. the brass nut was captive in a piece of rubber. The rubber was a loose push fit into the whole in the bodywork, but it expanded when the screw was tightened.
I got replacements from a local caravan outlet (but this was probably 15 years ago).
I'll look in the toolbox - if there is one there, I'll post a picture.
If only I could think of an original, witty signature . . . this is where it would be . . .
