Looking for input on using hand controls, a local puller was injured in an accident, and does not have the strength in his legs to be comfortable without some other ways to run the brakes and throttle. He has a duramax, the throttle is an easy fix. Just wondering about rules, and if anyone has any experience with running a hand brake setup. He normally runs in a street or work stock type class. I know there are dot legal setups out there, any input would be helpful.
