Radiator choices 26" or 22"

I actually have a Champion 26” 3 row in mine, not a 2 row. From where it mounts on the core support it’s about 3” into the engine compartment to the end of the tanks.

No “butchering” required either, just 4 new mounting holes. On mine I even welded nuts on the back just like the factory. Works great, I use a Ford Contour two speed, dual electric fan set up on it. Never had an issue, and I’ve sat in traffic when it’s 108* out.
Thank you, that's the measurement I needed
