Question about Interchangeable Parts (Radiator) Options

[Langing]

Sorry if this posting is placed on the wrong forum.

I'm not at all clear about what parts on the various 6G Celicas can be interchanged. From a junkyard, I took home a radiator from a 95 Celica, intending to use it in my 94 Celica. When I examined this radiator after getting home, I found that there are two nipples at the bottom that don't exist on the radiator of my 94.

I'm not sure but think the junkyard 95 Celica was a GT (it had a hatchback and spoiler), and might have had an automatic transmission while mine is a 94 ST Celica (1.8 L) manual transmission. There is a radiator hose going into my radiator, and a radiator hose coming out of my radiator, plus another small hose going to the coolant reservoir, and that is all.

From the two metal nipples at the bottom of the extracted radiator came a significant amount of dark reddish oily liquid that looks like automatic transmission fluid to me.

QUESTION: Would I be able to use this new radiator if I don't connect anything up to the extra nipples? Here is a picture of the junkyard radiator:



QUESTION: Is there any general guidance on this website about interchangeable parts within the various 6G Celicas?

The extra nips are for an auto transmission.
There is an extra small tank at the bottom for tranny fluid to circulate though to cool.
You don't need to do anything with them if you have a manual.

ST and GT radiators are different.
The outlet on the bottom is located on opposite sides ST/GT.

The one you pictured is an ST radiator.

Here are the differences in the bottom of the pics (outlet location)
