What's a good, lower cost radiator for a MK III?

[916MKIIIx2]

Alright its for the tranny cooler line, the connection on the tranny cooler is a female 1/2 in. NPT fitting, I either need to buy an adapter to attach the stock transmission oil line to the tranny cooler, or figure out what size the connection is at the transmission and buy a new hose and connections for both ends. So what type is the connection that connects to the tranny? Also... would an 8 -AN steel braided hose work for the tranny cooler lines?

Read that the thread size for the end that connects to the transmission is 12mm, can anyone confirm? Is that for the return and sending line from the transmission and cooler? Will I need 2 of whatever connector? Also can someone let me know if thats a female or male connection... and what type? This is pretty much the last bit of info I need to start this project. Also anyone with pictures of these connection points please post, I've seen pictures from only 1 person and they posted over a year ago on this same topic, just need to confirm a few things that were never confirmed in their posts.

Slightly off topic what diameter silicone hose should be used to join the throttle body and IC 3000 pipe together? mine is wearing
