I replaced it about a year and a half ago and am too lazy to find the receipt but I know it was over $400 and it has TRAD on it.
If you search TRAD radiators you can go see the interesting T.RAD website from Japan.
I am very careful about not leaning on it when working on the engine.
I tried JB weld and the steam pressure blew right thru it. I even roughed up the crack area to allow for a better epoxy grip.
In the end I called CDan and he sent me a TRAD radiator.
