mike,
i had a permacool, i used to have a pic of it in my gallery, but some asshole went through my gallery and now i only have about 1/3 of my images.
here it is on summit
Perma-Cool 12311 - Perma-Cool Maxi-Cool Six Pass Fluid Coolers - summitracing.com
it had nice npt thread so i made trans cooler lines out of braided hoses, much better than rubber.
