Radiator help needed for 67 520 swap

[datsunz]

Hi all, I ordered a water pump for my 520, the motor I was told was a 74 L18 from a 620, it looks like a 74 from a 710, the motor had the pump with the pulley and fan clutch, so I had to reorder. While I was at it, I took out the radiator and flushed the block out. The radiator looks worse out, patched, rotted. It says fomoco on it and the core is 17 wide and 15 high, after searching, I found it is a 74 pinto radiator, only made that year and unobtainable, searched the net, called everyone local, and one guy wants $308 to recore it. That seems high, considering I can get one shipped to my door for a 75 pinto for $100!!!. (same dimensions 3" taller) They cut out the latch area and mounted the radiator with pop rivets(sweet). So I wanted to put the same one in. Any suggestions?

Thanks
