I really like the nostalgic look of the low back seats in a Cobra but one of the problems is you have no neck support if the unfortunate happened. I started to look on the forum and found a mod that I really wanted to add to my build. I wanted to add a headrest and found another builder (Skidd) used a wheel chair calf pad which turns out to be cheap and about perfect size. I then took the pad to my upholstery guy and had him cover them with the leather hyde I am using on the car. This was relatively a cheap mod, about $150 total with all materials including upholstery.
Here are the wheel chair calf pads I picked up:

These are the rollbar clamps I ended up using:

After mounting the roll bar clamps I mounted the base plate for the head rest. I used stainless hardware for the install.
I cut a piece of 2" wide x 1/8" alum stock I had in my garage. It is a good thickness for this application, plenty strong. I ended up using 500 grit and wet sanded it down and followed it up with some Mothers metal polish. Once the brace was mounted I used the 4 bolts to affix the head rest to the base plate. I went with black bolts I picked up from Ace hardware.

The roll bar clamps have nice thick rubber grommets to protect the chrome on the roll bar. They can easily be adjusted up and down on the roll bar. They are not fully tightened down in this pic, they will pull together even more at full clamp force.
