FYI VistaPro Radiators from Advance thinner than OEM

Beware: the VistaPro unit from Advance is thinner than OEM, does NOT come with the top and bottom brackets, and and you have to modify the OEM brackets quite a bit to get them to fit.

The Spectra Premium radiator that I got from Amazon for my car was actually THICKER than the OEM unit by a hair, and it was a good fit. All I had to do was trim the rubber feet at the top fan shroud to get it in.

I know you're dealing with an LT1 car, but they might have an application for you guys, too. FWIW.
