The flat area right below the dash "pad" will have custom billet inserts made by these guys

Try to fab ac vents today-remove original key hole-wiper hole next to cluster-that curved piece in center of dash(bottom) will house a Doc's Kustom
piece for controls and a vintage air controller
Really have not decided on "tunes " yet---Anybody lead me 2 a radio that I can hide with only remote control fob?? LIke to keep dash as slick as possible......jim
