just read through this, the car's going to be great when done. re the rad/fan combo, it looks like the fan mounting 'plate' is backwards on the rad. if you swap it round there'll be a gap between it and the core all over allowing the fans to draw from the whole core not just where they're up against the 2 spots (and the flat areas of the plate won't be blocking the core). i know it'll push the fans back toward the motor some but that should be allowed for if it's a 'package' type deal. you may have this sorted by now but i thought it worth mentioning.
