<VV> How was the VIN assigned/attached on 69s?

[dave at arborlea.com]

Dave - thanks for an excellent explanation.  That makes sense!  I had not
realized the instrument cluster and dash assembly were Chevy items and not
Fisher installed.  I would assume the dash pad was Chevy also, which would
have allowed the VIN tag installation prior to it's installation.

It never occurred to me that the dash would not have been done by Fisher -
seems like a body part to me :-)  Had I looked at the assy manual it would
have been obvious I guess.
