Limited late model roof clarification

After some questions, I wanted to clear up the rule on the roofs for the Limited Lates. There are only 2 roof options for this division. 1st is the Standard pavement style greenhouse and the 2nd is the Outlaw style roof with windows front and rear. Outlaw roof will have a 50# weight penalty and a 1" reduction in the spoiler. The roof must be made of fiberglass. These are the only 2 options.
