no they did not use the same shroud the 63 radiator flowed up and down and was narrower then the cross flow used in 65 64 was a switch year on these might or might not have the same shroud, depends on the way the radiator flowed Greg
I stand by my statement, 65 Riviera's did not have crossflow radiators, they got them in 66, the big cars got crossflows in 65. Kevin
