Ryan - The intercooler is out of a ford powerstroke, fits inbetween the headlight assemblies nicely.
Engine mounts I purchased from Kenny at AutoWorld in Montana, he said to grind on the IFS diff for clearance but I raised the frame mounts 1 3/4" to alleviate grinding. This way I was also able to notch the frame for the A/C Compressor, havent hooked it up yet but hopefully be able to.
Transmission is the 5spd and I didnt have to move the crossmember either, used the stock Dodge trans mount.
As far as the cluster I didnt want a 6,000rpm tach so I just decided to go the custom route.
The box next to the rad/intercooler is a electric fan controller, I mounted a ford powerstroke radiator under the bed flat as a auxillary radiator with two small fans on it to help keep it cool pulling the 5th wheel over the rockies.
Everything else was simple, no other tricks that I can remember other than if you do twin turbos you need to cut away some of the passenger floor and hump it up for the 5" downpipe, you wont even notice it when you flop the carpet back down.
Any other questions let me know.
