I got mine about 2 years ago from mid fifty f 100.  It is steel  o e style . Make sure you use a 4 pound pressure cap. They will  not warranty the radiator if a higher pressure is used.  Hope this helps.  Joe

Does anyone out there have a good radiator for a 63 f100 for a 292. Mine has been repaired about 3 times now and it keeps leaking in a new spot every time it gets fixed. And now they is no place near me that even fixes them. I prefer to keep it original rather than going with an aluminum on. Please let me know if anyone has a good used or NOS radiator.
