I have already got the inside quarters out for molding of the box. I have already lined the rear w/ dynomat all around and was thinking about doing the rest of the car but I don't want to add too much weight. How much does that stuff weigh any how? I am building the box to be easily removed for racing and etc... Thanks for your help peeps I appreciate it. Jimmy Kost 1999 Eclipse RS (White) Overland Park KS gtagrp1@earthlink.net
