I am continuing to restore the interior of my 1976 Cadillac Superior ambulance. Members of the Franklin Lakes Ambulance have advised me there was a wood backboard mounted under the full length squad bench. I have found some Superior advertising which shows a small backboard under a partial length bench, but no backboard under a full length bench.
The attached photo shows what I believe were the two brackets to hold one side of the board. (The white papers are just there to highlight the brackets and knob.) My question revolves around the 3/8-16 thumb screw at the other end of the bench. How did this anchor the board? Is there a missing bracket or did the screw go through a hole in the board? I have searched Superior literature, but have been unable to discover an answer.
Before anyone comments, I am a NJ EMT Instructor so I am aware of the recent changes in spinal immobilization, but still want to make a board for my ambulance.
