Looking at one of these jobbers. I believe something is different, but not sure what? http://www.usradiator.com/radiators/buick?cat=2047
Can’t tell what is different but something is. Checked Buick spare part number and they are not the same for 62 and 62. Bought a Champion alu radiator that is supposed to fit 61-64. It fits my -61 but it is not a perfect match.
Well I bit the bullet, and bought one of those high dollar US rads. Also found a guy local that has the shroud, brackets, and rad out of a 62 so I'll know for sure this weekend.
