Hi Tim,
I purchased one of these (can't tell if exactly the same as link now does not work).
It was certainly not the same as the original radiator and presented significant difficulties in attempting to fit it into an FC.
I first tried it in our ute, due to the extra thickness it had less than 5mm from the fan and the top and bottom tanks fouled. The mounting holes were also out of place.
When I tried it in our sedan there was a little more clearance to the fan but only just enough... Same problem with fouling and mounting brackets. After some subtle modifications I have installed it in the sedan but certainly not happy with the result. Will stay until I can get an original one re-cored.
My advice would be to buy one only as a last resort and be prepared for challenges
The Ebay vendor was prepared to take it back based on no damage and original packaging which is a bit hard as mine was vacuum plastic packed and of course as soon as you try to slide it into place you touch the fins against the radiator and so it looks damaged.
Cheers,
