Have been researching low profile radiator to suit my trike Subaru engine
Likely will settle for a Porsche 911/996 centre radiator 610x170x41mm
But this one is from a Fiat 600 abarth that is an auxillary radiator. dimensions about 580x80 and can fit under a car.

Might suit your VW project as a back up rad?

Thanks for the link PAZZAN. However the Porsche "centre" radiator is only 170mm high. Height is my problem. I need a radiator no more than 200mm high and as wide as 750mm. There is nothing between the porsche height at 170mm and jeep cherokee at 270mm. So porsche it is and only $250 landed in oz from USA it is ideal. it will need 6 inch thermo fans at $49 ea on ebay.

Lucky that radiator is 41mm thick, making it efficient enough to cool the ea81.
