Replacement sunroof for MX3 V6

[z_rawi]

Where can one buy replacement sunroofs from for MX3's please, mine is getting a bit rusty at the back. Also why does this happen, does water get inside somehow?

I believe you can buy a carbon fiber rx7 sunroof. Not sure if fc or fd version.

I might not be a cheap solution as its carbon.
