I have plenty of oem coolers, 99- mid 01 all aluminum, late 01-03 plastic tank, 03-07 6.0.
The 6.0 is 3 inches taller, 1/4" thicker than 7.3, p side connection same size as 7.3, driver is 3".
Just so you know if you find a banks cooler for 94-97, it same as 99-03 core.
I'd sell whatever oem you want for 150.00 plus ship.
