<VV> Harmonic Balancer Manufacture print

[RUSSELL DAVIS]

Does any one in V V land  have the General Motors dimensions for the Corvair harmonic balancer I.D. bore including the plus or minus tolerances? A print would be nice!!!!!! I have contacted Bob Helt about this and he didnt have any info  Bob Coffin does not have a print either.
  Thanks in advance for any info.
