I'm considering putting on a 300ex carb onto a 250ex. I want to make sure the metal piece that bolts the carb onto the motor is the correct size

can someone take a measurement of the distance between the threads that a 250ex and a 300ex carb each mount on?

any help is greatly appreciated!!!

Thanks,
Ryan

the 300ex mounts up using a rubber boot, not a metal intake.
