If I'm honest here Bill, the bit that strikes me as not looking quite right is the cutout in the top of the bumper. I agree with Shayne to spray the cooler black which is what I plan to do with mine if I ever get the job done.
Your mesh mod looks ok, but again I feel would look more discreet sprayed black, or if available, the same colour as the original grille. I'm not so struck on the eBay one as to me the mesh looks too big. If I were to build one or do a major mod, I think I would put slightly angled stainless louvres in with around a ten degree downward slope into the whole grille and spray black or stock grey.
Did you find those photos of the pipe work from the cooler back to the engine? Would be good to see the routing and what fittings I need for doing mine.
