SPF has glass rear windows

[Steve C]

Have seen questions re what SPF is using for rear clamshell and firewall:...both are glass not plexi. Steve

 

[Ron Earp]

Most cars have options of either. All RFs were glass for both, CAVs can be either, as can RCR, ERA, and the others. I think people have a tendancy to see one data point for a particular car and assume that all from the company are built like that but nothing could be further from the truth.
