The 'New' Champion 374

Ok so I just measured and mine is in fact 23 5/8” from the bottom to the top of the radiator cap. When I installed it, I put a chunk of play-do on the cap and carefully closed the hood. I had 3/4-1” clearance.
What year Duster? I have a 74 and the cap sits 2 inches above the core support. I'm concerned about clearance. I don't want to complete the install until I'm sure it will clear. Thanks.
