Welcome to RCTALK.COM!!!
It looks like this car has panels that screw to the chassis directly. Is that correct?
If so, perhaps 3d prints of other styles are availible?
My thoughts are to look into lexan alternatives.
I recommend taking a measurement of your wheel base and width so you can determine which size bodies might fit.
You can contact teambluegroove.com about your project. They can help you figure out what fits too. I strongly recommend this route if lexan is your goal.
Sabula tech, Parma, Leadfinger Racing and McAllister are all great sources of Lexan too.
I have personally dealt with TBG. They are AWESOME to deal with though sometimes a bit busy so slow with email sometimes.
They are in Canada too so bodies cost less in US dollars.
