The oil cooler part is not that difficult. The adapter plate will have to be cast. Just find a suitable automotive oil cooler, weld on some brackets, and purchase an adapter plate from any of the vendors. I'd contact dratv.com to see if he can get just the adapter plates, as I know he can, but if he will, that's a different story.
To make a mainstream oil cooler for the masses is a great idea, once you get the adapter plate worked out. I wouldn't fabricate one off the existing plate, just purchase one and copy the sucker.
