After I made my last post I bit the bullet and ordered one of the good eBay fully wielded aluminum radiators from http://stores.ebay.com/Speed-Daddy-Com/_i.html?_nkw=Datsun&submit=Search&_sid=841766438 . It's nice very good build and came with two 10 inch flex fans it is a down flow. Due to the fact I am not pushing over 400hp it will due just fine. ( over the 400 hp mark I would recommend a cross flow ) I can not wait to get it in and see how it dose. And here are a few pics.
