I understand everyone's concern about the frame. I have been doing this for nearly 30 years now and have never had a weld crack, even on some very high horsepower trucks. Remember, this is a C20 and the frame rail is about 50% thicker than a C10 frame.

Skinning the rail with a channel that fits inside would be insurance that everyone can see and understand. Welding is still mysterious to most and not trusted with your life. I am a unlimited thickness certified welder. The frame will stay as is. All others please add fish plates and not follow my example here.
