Kenworth specs

I'd consider a pick and pay junk yard because your going to need new tank straps for the the larger diameter. All added, that's going to cost $. I've gone to Steve's Truck and Equipment in Mitchell, NE a few times. I pulled and bought tank skirts with the straps once there, and at a good price! Steve's has a location in Scottsbluff 10 miles away also. But I don't think there is any equipment there. As I imagine you have thought of, plan on maybe installing new fuel lines and fittings.
