Hi, I want to use these to possibly make fender well headers on my 61 olds gasser. What is the furthest they will reach out on dimension A with the 90's? I'd like to make them reach behind the front wheels.

dimensions of part # 91013168 I need to know the header chart dimensions A and B. These headers look like they will work for a vintage open wheel center steer dirt modified I'm working on. But the frame rail could be close, with A and B I will know the headers will clear. Thank you, Jamie
