You can probably find a local plastics shop that can make you a new one out of acrylic.
Sent you a PM.
Do a search on hatch or cuddy hatch and I think you'll find some other members that went through the same process you're starting.
Not sure what happened with the PM:Try Plastics America on Adamo Drive in Tampa... take your original and they can make a copy for you out of whatever material you want. Ive purchase a bunch of lexan/starboard/pvc material from them- good prices and easy to deal with.
