TRY THESE GUYS... http://www.universalpartsinc.com/
they have an ebay store too.

Be warned I am not sure if they make all their radiators or not. I bought a special ford 28" wide 16" tall crossflow (2-1" cores) with built in oil cooler from them for $290. That is a very good deal in my opinion. It showed up at my door with a norther radiator sticker and an invoice of $175. So they made $100 bucks off taking my call. But, they were the cheapest I could find that met my wishes.

You might also try a custom fabbed radiator from Air Mobile near dunlap and 7th street. They are about $300 and you have someone local to complain to if you have a problem.

and yes, I chopped up my radiator support to make it work and it looks sweet.
