Check out Derale Performance. They have the "Good" stuff, not the cheapy 30 buck garbage.
They carry all different types, sizes, clamp on stule, and the good AN fitting type hardware.
I replaced the oe Ford trans cooler, 13 row, with a Derale 40 row stacked plate design that has 3 times to btu heat dissapation of the oe unit.
Not cheap, but not overly expensive for the quality you get.
