I've found plenty of listings for dual+ core rads for D50, but none state years or compatibility, let alone dimensions. Can anyone help with size so I can find an aluminum replacement? Thickness counts here, I have limited clearance on my fan (though some headroom by moving it around). Am I wrong to think that Starion/Conquest rads would work?

Have found a few clutches, both 2 and 3 stage, but not sure what I would want. My assumption is that 3 stage would be overkill and suck bad with a cable? If so, what brand of 2 stage? CenterForce and F1 seem to be what I find, F1 being much cheaper. Any other choices?
