If you're looking for a 914 tribute project, tough to find.
But if you're looking for something functional for a current race car then look for ones made for an SCCA F Production Miata, they're out there. I'd not be surprised if one can be modded to fit the 914.
Edit: Disregard: Craigers posted the below.
If "tribute" then this can be used as a mold to lay out an appopriate Lexan panel.

I'm guessing you're not looking to buy new, but if so, these guys appear to have them. Good luck!
