where do I get one of these

the problem with shopping around especially here is they want to see the old radiator. By the time I run it by all the shops I will have spent that much in gas. They want so much info on the tank, core size,header size,tube size. what ever happened to calling up a shop and telling them I want a 3 row built 26x18 core using my tanks. everything has to be so difficult anymore.
