3-Point Hitch Lift arm length

[ClemsMT372]

Hi,
I just bought a Mt372 tractor but found it does not have the 3 point arms with it. I was wondering if anyone knew the length of the arms and if any arms from something more common like a Kubota or Yanmar would work?
Thanks
TC

did you ever find out the length? Or does anyone know the length?
