Re: GMC vs Chevy radiator differences/depth

If you go too far forward you have to do something with the cross brace and panel in front of the radiator

Yellow shows the radiator sitting forward in the core support

Middle one is GMC Making me think I can use my GMC radiator support with the cross piece of a Chevy radiator support or a custom cross piece.

The blue one is the radiator in the stock position in the Chevy radiator support, note the piece in front of the radiator to block air from rising up and over the radiator. That shows how much space you have available.
