A question for those in the know , My oil cooler rotted through and i can find PSD coolers alot easier than idi's My question is the tube part only the same for IDI as the PSD ? My aluminum end caps are ok . In researching i came across this thread but no one confirmed or denied that it would work . http://www.oilburners.net/forums/showthread.php?66489-Oil-cooler&highlight=oil+cooler
