Manual trans radiator fit in auto truck?

[Joelvv]

I need a radiator for my 2000 K3500 w/ 5.7, and an OSC is available to me through amazon for a manual transmission. It only looks to be missing the trans cooler, which I'm not using anyways. It still have the engine cooler. Any reason it wouldn't fit? I can order the proper one throught rockauto, but I'll plug the trans cooler anyways, and it's $80 for shipping.
Never mind, the manual trans radiator has a 1" core vs a 1.25" core on the auto trans rad.

There are two different styles of radiator mount on the top of the support, one set is short and one tall. If the radiator is the same height it will physically interchange. Other considerations would be heater hose return fitting, trans and oil coolers.
