Does anyone know if you can run a fuel cell in a wood bed?..and still be legal to run down the track.. I have a wood bed in my truck now and if I have to change it over what is the easiest way to do it? Beside swapping the entire bed.. Also whats the best company to buy parts for a dana 44? Gears, posi unit ect.. I have a dana 44 in the rear of my 2 wd 68 GMC.
