Car - adm ae86/sprinter

motor - FWD 4age smallport (ae92)

use - conversion

problem - radiator/thermostat

occurs/started when - doing a 4ac - 4age conversion

personal situation (if applicable)-

So I am just getting ready to change this engine over and was wondering if someone could tell me what is the best way of moving this external thermostat closer to the radiator? I'm thinking just get longer radiator pipes. Is it that simple? Or would i need to mod or fab something up to make it suit my 86?

I'll have to run it through the heater core too so it passes rego. I've tried searching the forums but couldnt find any helpful info so if someone could please point me to a thread they know of or give me some advice here it would be much appreciated. Here are some pics of the engine's current cooling system setup. Thanks!
