Hello steve . following your build with interest as I too am building a 3 window but its a chev . I was thinking of getting some 32 American stamping rails and I like the way you have boxed yours . question for you in relation to our cert process is the welding of rails , is this done under compentacy or do they require certed welding . the hotrod hobby car book says I can weld them being a competent welder but ive been told by other rodders I cant .. . what process have you followed here . the only welding that requires cert that I can see is when a the weight of the vehicle is in question . eg suspension . ? thoughts from the south nz .
