Mounting configuration. 126 has vertical flow with the transmission cooler in the bottom tank. 124 is crossflow with the transmission cooler in the side tank. The hose layout is slightly different too, the 124 has the coolant expansion bottle hooked up to the radiator, the 126 has the hose for that purpose splitting off from the lower radiator hose.
Subtle differences, but enough to cause problems for installation without custom fabrication.
