ZeroG's install looks much cleaner. The expansion tank mount in that first link looks waay ghetto. (I especially love the comment about using OEM zip ties!).
I have this same radiator sitting in a box in my garage, but haven't gotten around to installing it yet. A while back, I picked up a solid brass overflow tank from a Range Rover in the boneyard- I think I'm going to glass bead it, polish it, and mount it somewhere on or near the fender well.
