I bought a slightly beefed up radiator from A&A corvette. Looking at their site I dont see it listed anymore though. It uses the stock end tanks and an about half again thicker core. It was $250 or thereabouts IIRC and is a direct fit. Here's a pic showing the difference in core thickness. If interested you should call A&A, they may still have it avaialble and just not listed on their new site.
