Jon,
Don't sand it down! You're break is beyond the glue joint - if you sand it down it will shorten the length of the lens & when you try to fit it...it won't!
I swear, the Germans tried to make plastic & vinyl pieces irrepairable!
Depending on your use of the car, I'd try Gorilla Glue - it is a remarkable product. Yes, you'll be able to see the joint, but unless you just buy another lens, I think that's the best you can do.
Here's what I think causes this problem. Too many people put the lenses in place, put the tightening screw/buttons one & carnk them till they won't crank anymore - trying to make them fit too tight against the gaskets. Put that kind of stress on any plastic/butt welded piece will eventually cause it to stress & crack.
Whatever you use, let it cure, then screw it down in stages, until you have a reasonably tight seal - not until it cracks again.
For my money.....I'd get another lens. BTW, why euro lenses? Was your 914 a euro delivery? Does it have side markers?
