By "notching" the squart tube sub frames I refer to the process of cutting a half moon shape out of the offending area of the SFC. It should only require a cut through the corner of the square tube. Then fit a half round piece of steel pipe large enough to easily pass the fuel line through the SFC at the corner where it is near the floor. Then weld the steel tube into the SFC and ground smooth.
I don't know a lot about anything, but I know a little about everything.
Built a 1967 Shelby GT-350 Convertible Replica, a 67 Vert resto-mod and also built a 427 FE 67 Shelby GT-500R (R Stands for Replica). 427 Side Oiler, toploader 4spd, 4 wheel discs, 9" traction loc and a perfect body. What more could you ask for? Now I car hunt and horse trade and I am currently looking for the next project! Always seeking that elusive "reasonable" Shelby.
