What mike said then take your time measuring the pillars to be cut.

Figure out your glass first, For example; Tempered glass (side windows and rear glass) cant be cut but laminated glass(Windshield) can be cut or trimmed. Getting curved glass built is extremely expensive. Trying to retain your stock glass is the cheapest way to go, but sometimes imposible Blah Blah Do your research, check IF customs website to get ideas. And like he said ^^^^^^^Take your time measuring, unless you want a roadster. Or theres always Plexiglass if you dont mind it.
