This underdash mount is designed to securely mount your ididit column to a 1969 or newer GM passenger car columns. Mounting slots are set 5 1/4 in apart (slotted 1?). Each dash mount has two clamp bolts located on either side and when removed will separate the drop halves allowing you to slide your column through. They have been so flawlessly buffed that the split between the two pieces are nearly invisible.
