Ive recently come into a huge hole in my radiator after running through a flock of birds. My car is a 1981 pontiac catalina, Big old GM B-body like the caprices, etc. What would be the best place to get a radiator for it? Not really looking for new because i dont have the money, how much do junkyards usually charge? And would anyone happen to know of other radiators that will work well?
