This car will be a stud. And this obviously isn't your first rodeo with fab work; impressive.
Just curious... being from MB, SC, are you familiar with the Classic Car Musuem in the area? It isn't advertised as a Mopar exhibit, but out of the 40 vehicles on show, about 35 of them were 1967-1970 Mopars. (1 owner who is now displaying his collection. 90% are former drag cars that are original and unrestored!... While on the tour, a visitor asked the owner why he had "so many Dodges and only 1 Mustang?!?" The owner smiled and calmly responded... "Well, I liked winning".)
Best of luck as you keep building your E-body! I enjoy watching the progress!
