Don't know if 67 vs. 66 is the same. I have a 1966.
I went through this in a panic a year ago. Radiator shop couldn't get
new core to fix my old one. Radiator shop wanted $500 for a "custom"
manufactured replacement radiator. No thanks. Radiators on E bay were $225,
but were aluminum from China. No thanks. I found a new copper/brass three
row radiator for $186.79 from Rock Auto (
www.rockauto.com) supplied by
Proliance, made in Mexico. Ended up $207 with shipping. The radiator has
connections for auto tranny cooler that I didn't need and was slightly larger on
the outlet then my original (1.75" vs. 1.5"). I am well satisfied. One note
on measurements that I learned is that they don't include the tank. You need
to add the tanks to get overall dimensions. Here is the info from the
Proliance site and the part number for it:
