Underdash Mounts are designed for several different applications from a '65 Ford Truck, '69 or new GM car or even your '32 Ford. For the swinger style drops the underdash nuts & bolts are included. Each swinger drop has two screws on either side that when unscrewed will detach the lower half of the mount to slide your column through. They have been buffed so well that there is no noticable gap between the two pieces! Each piece was manufactured in the United States by ididit.
