the radiator that champion list, says it will be 22.62 tall. that would fit...but the one i got is 1 1/8" taller than spec'd, that don't fit. they don't know why, and don't really seem to care..
If you look at the Heating/Cooling/AC Forum here at FABO, you will find a ton of information about aftermarket/replacement Radiators for our A-Body cars.
