Steering column clearance to headers

I am currently building my own 68 super stock clone Barracuda, and I am in the process of mounting my brackets to the K frame for the engine. I am using factory style reproduction mounts, on a clean v8 k frame, with TTI headers. I have followed their instructions, and would like to know if anyone, could tell me the actual clearance they were able to obtain between the steering column shaft and #7 pipe. Also has anyone had to move the steering gear box outboard to obtain clearance for this location?
