Radiator core support differences?
Does anyone know the differences between a 72 BBC radiator core support and a 75 Radiator core support?
I know the openning for the 72BBC is 27 1/2" wide X 17" high.

Almost certainly the opening for the radiator (bigger for big blocks) and the fan shroud attaching apparatus.

I know the openings for the big block is wider and GM changed the lower radiator straddell in the middle of the 76 year. I guess what I'm looking for is the opening size of the 75 radiator core supports. Wilcox has some dimensions shown on their web site just not the one i'm looking for. Thanks
