2021-01-03 - Lexan Fastback Window

By rule we are allowed to run a lexan rear window. Can we re-locate that rear window to our fast back for no material points?

Currently we are claiming material points for the fastback.

You can use a lexan window in your fast back that is the same size and shape as the normal rear window. It can only be used as a window, it cannot be repurposed.
