Nate,
The a/c condenser is going to be very visible behind your grille, so that one has to be black. I have not looked at all that many, but the under bumper ones I have seen are black.
Almost 6 years ago I found a company in California that had the main condenser in stock. Theirs is aluminum with twice the number of tubes of smaller diameter as the stock model. This provides much better heat transfer and keeps the same volume. I recall having to file out on of the mounting holes a tiny bit, but otherwise it was a drop in replacement. Cost then was $180.00 It was silver and I painted it black. I just spent several minutes looking through my receipts and couldn't find the company name. It might be worth an internet search for companies that manufacture condensers.
