Pic Request - 2WD Trucks with Long Tube Headers

[axisT6]

I searched, but couldn't find what I needed. For those with 2wds that have longtubes, could you give me a measurement of the gap between the collectors (part where the primaries join) and the chassis? I am thinking of re-doing the SAS brackets on my truck and want to see if I can clear long tube headers.

Thanks for your help.
