bearing carrier OD / caliper bracket Q

[atvmxr]

can someone tell me what the OD on the 450 bearing carrier is where the caliper bracket slides on, or the ID of the caliper bracket? I want to use a 450r bearing carrier as part of the 450r swingarm swap on my 250r and want to make sure I can use the 250r caliper bracket on the 450r carrier.
thanks

2.744" for the OD

Swap the brake too. I've had 450R rear brakes on my 250R for about three years and they work great. Much easier to change the pads too. See the sticky in the 250R forum.
