4 barrel culvert 6.5 miles from the Cordes Junction southbound exit. Moving to AZ from OK in 1986 my `77 VW Scirocco broke down just before that exit. I converted the fuel injection to a Holley Carb cause that's what kids do. Modify stuff, yeah even if it goes against common sense. Dad and I had CB radios to communicate but he was long gone with a non kid modified sports car. My self rebuilt carb fell apart... lol
