It would help a lot to know what the plastic is. I've written to
GiviUSA but probably won't get an answer till well into the new
year, if then. Somewhere I got the idea that Givi cases were made
of ABS, which can be glued very well using solvents. If that's
true, a sheet of ABS affixed with solvent cement might be a
fairly good repair. I posted in large part  hoping somebody
on these lists might know. So far, nobody's offered a clue.

Thanks for writing,
