I do not have one but you could build your own very simple if you still have the casing. last year I rolled over a branch that broke my turn light. I was able to fabricate a mold from styrofoam . I then used the same material they pour over bar tables. . it sets real well . just add paint to the mixture.
Look up PIAGGIO PORTER on Ebay. They are in Italy and don't speak good english, but I ordered a set from them for my 93 and they were able to combine the shipping. They fit perfect and were cheap. Colored a little differently but who cares.
We can get one for you . Easy to look up your hijet build sheet with your chasis number. Let me know if I can help. Regards, Danny
