I call it a Ness bar, because the first time I saw that wrap around shape to tie the main hoop, down bars & rear struts all together was on a Don Ness Pro/Stock car in the 80's. I do it differently on my Track-Warrior tube chassis cars. But on Craig's Cuda, which still has the floor & already had a roll cage this was just another way of skinning the cat.
P.S. Looking good Craig !
