So I plan on doing a rear tube chassis with my G35, and wanted to replace my rear quarter panels and rear end with a plastic/polyurethane replacement panel.

they sell pieces like these for BRZ, 240sx and other cars.

I cant seem to be able to find these pieces made for the G35. Probably because the G35 isn't used in formula drifting or other auto sports as much as other cars.

If you guys dont know where I can buy them, do you know someone who can make them? or a video explaining the process so i can make it myself?
