Darren,
I’d had have to see it to be sure, but I think it could be done with some Permapoxy Plastic Weld. The stuff is amazing and smells about ten times worse than PVC glue.

I have used it to adhere plastic to metal with outstanding results. I got mine at the Kmart on Clearview. (Elmwood Shopping Center)
I’m 10 minutes from the track if I can help you let me know.
