Caravan Handicap

Caravan Handicap
Can anyone with handicap hand controls for their car tell me how it connects to the brake?

I have push/pull controls in my caravan but I don’t have the part with the 3/8 rod that connects to the brake. Is it clamped to the brake with a U bolt or does it use some other method? Does anyone know where I could get this piece?

i had a jeep with hand controls the brake pedal was drilled and had a cotter pin holding the rod in place
