Can check Summit also for Hayden 2765: 2.67" height.

Was also going to suggest like @RustyRatRod is talking. Take a Porto-Power and push the core support forward 1/4" at the left and right radiator mounts.

Core support is just a tin stamping that can move pretty easy. Should be plenty of room at the hood latch adjustment to allow for it to move forward. Loosen the bolts on the radiator mounts as you don't want to tweek that when adjusting the core support.
That's the Jaguar XJ6 application.
