Harmonic Balancer

[althomas55]

I am trying to determine the correct part/casting number of the harmonic balancer that would have been used on the 68 MO 302 engine . Does anyone have one they would sell ? I believe this should be an 8 in dia x 1 11/16 wide balancer ? I have seen some with fins on the inside which I believe to be earlier vintage and some without fins but cannot seem to find info indicating which is correct for the 68  MO engine

There are some photos of a '68 Z/28 harmonic balancer posted here...

The correct part number is 3817173 and the original Z/28 ones do not have fins.
