Ray Parker did it
Jody,
Ray Parker put rear rudder pedals with brakes in the rear of his 8A. He used part of Vans rear rudder pedal kit, but made his own rear rudder pedals. His brake set up is rather ingenious. He was nice enough to send me a few photos.
I decided not to bother, but have saved the photos. Contact me via email and I'll send them to you. To get my [or any member's] contact info, left click on my user name [at the top of my post]
