Need a measurement on E body ASAP. Radiator to rad support height.

Not an A body but I already posted it on the E body forum and figured I would double my chances.
Im in the process of custom fitting an aluminum radiator in my 71 cuda. The radiator bolted in fine but needs to be raised up quite a bit to use the factory shroud. So im looking for a measurement from the top of the radiator support to the top of the filler neck. I measured with the factory radiator and it was only slightly less than 3/4"....not enough. I measured my all stock 73 dart sport and it comes in around 1.1" My 73 swinger measured 1.9" and it still has clearance to the hood. I assume the A bodys have about the same clearance but I dont want to take any chances here. The first pic shows how im measuring. The second pic is a mock up with the minimum height I need to make the shroud fit.
