At the time, if the client was employed, and owned a vehicle, the State of Massachusetts would pay up to $35,000 for the vehicle conversion.
We had one client - a thalidomide baby, whose hands were connected to his shoulders, without arms.
With his magic ring, he would wave at a certain part of the van, and the door would pop open, he'd climb into the driver seat, and be automatically strapped in, slip off his shoe, and insert his foot into a holder on the floor mounted steering wheel, and a row of toggle switches on the floor relayed everything from the dashboard, even to the bass/treble radio balance to be operated by his toes.
Should'a seen this guy drive. Absolutely amazing. He could even zip up his jacket by hooking a toe in the zipper pull, up to his throat.
This job gave me a whole new perspective of the adaptability of people.
I had a friend lose his leg in a motorcycle accident & had a conversion bike built. He still rides.
