If you want to eliminate the cardboard shroud in front of the TR6 radiator - increase air flow around the engine - but maintain fan draw - I have installed a radiator fan shroud from a toyota PICKUP 84-95 gas truck - its black poly and is a very close fit to the TR6 radiator dimensions. I cut out the upper and lower hose connection area (a 45 degree cut) with a sawzall and trimmed out the fan circle to be flat so it does not hit the engine side. Just screwed it to the flanges on the radiator sides with self tapping screws. Works amazing! - I live in SW florida - its hot here in the summer - my temp gauge does not move in traffic - stopped at lights - you name it. Best part - it costs under 20 bucks - I got it online at carpartswholesale - but any aftermarket place should be able to get it. Much cheaper alternate to electric fans - and if you want to route a ram to the carbs - the engine bay area is wide open.
