Don't waste your money on a tube and fin type, they are not very efficient. The stacked plate ones are a lot smaller, and the air passes thru them on a 45 degree angle, making them even more efficient, as the air is slowed down, and in there longer, for better transfer of heat.
Holden dealers sell them, part number M41535 for hose clamp ends, or M41536 for threaded fittings. I used a threaded fitting one in my Mustang, with braided lines and fittings.
It is currently in front of the radiator, but I will be relocating it to the right front wheel arch, behind the tyre. Much shorter travel for the hoses, and better looking from the front.
