Al,
Mine wasn't to bad, probably have about 8-9hrs into the intercooler itself. Your truck set up for the factory intercooler and cross flow radiator is a different animal though. The uprights for the radaitor look like they are going to be in the way. The second gen cooler pretty much eliminates the possibility of installing A/C. I had to cut about 2 1/2" from the back of the grill and modify the hood latch support to make it fit.
I took pictures of the install with the shops digital camera. If you want them, PM me with your address and I'll burn them to a cd and send them to ya.
Later,
Paul
