Heres the dash install..... the middle speaker grille covers the defrost vents, (its a convertible, so we figured in this case form over function! plus we kept the side defrosts that came stock in the ctsv)
The side speaker grilles are for the tweeters. these are modified ctsv vents. Overall we took about 8 inches off the dash and made a sheet metal edge for the leather to butt up to in place of the factory 69 camaro dash. complete with a vin tag spot!
