Are the mounting points on a 240Z and a 280Z for the radiator the same?

Are the mounting points on a 240Z and a 280Z for the radiator the same?

I put a 75 280Z radiator in my 71 240Z and it bolted in with

out any modifications to the car. However the radiator will

hang below your lower core support. The radiator mounting

flange has the same bolt spacing as the 240 but it to be

ground so it will fit between the 240z's frame rails. All in all

the 280Z radiator will work but the bottom tank is a a

vulnerable area. I cut a piece of 2in square tubing and

bolted it to the bottom of the core support to protect

the radiator. The lower radiator connection sticks straight

out and is not curved up like the 71. The upper is the same.
