Was wondering what are the rules on window's and window nets i was thinking of removing the side door windows on my 87. and replacing them with window nets. Do i still need to have some type of lexan in place or will the window nets do. Just a FYI the car is getting a 8 point cage now i was going to make up some of the added weight by removing the side windows...thanks for any info. also were do they want the nets mounted to, to pass tech ...thanks
