Cold Case Radiator what fan and shroud are you using ?
Just for other A body readers info. Cold Case makes a direct fit unit for hte 67-69 A body which your oem A body shroud will bolt right up to. However, when a customer wants a full kit from us, we recommend a different 22" Cold Case model. That model is a hit or miss on clearance because of so many factors. So if you try and use this 2nd model with a factory shroud, although the rad will fit the support properly, the shroud is not going to fit without mods.
I hope this helps.
