The closest I have come so far was I found a shop in WA who posted on FB custom work they did on an SVX. I emailed the shop asking about details to the best of their recollection. They said they did the following:

Aluminum Koyo Radiator - VH091672 (Appears to be fit for an STI?)

Had to install an transmission cooler since the radiator did not have one (since it was meant for a manual)

This model was able to use the mounting points/components of the original radiator to get it fit in place.

Since separate transmission coolers are recommended anyway, that part doesn't seem like a big deal. It seems to be good news that it will mount without crazy cutting / drilling to mount it. I guess the big question is whether it is adequate to keep the engine cool.

I'm assuming it is if they are saying it worked for this customer?
