Wow, that looks really good!!! I think that you are going to be really happy that you went with the thunderbird radiator, not only does it fit better but it will also do a better job at keeping your engine cool. I've got the same one and it keeps the 4.0 plenty cool, at least so far. Now that you are getting to putting in fluids, I'm curious what you plan to run in your tranny, transfer case and axle gears. I'm getting ready to do my +/- 100 mile flush and want to start running some good stuff in all those locations, right now I'm just running napa gear oil. Did you learn anything cool in that class on oil you took?
