Were is the serial number?

[rob love]

The CFRs were not stamped onto the frame in the late 60s/early 70s. That seems to have been a trait from the late 50s or very early 60s.

Best bet is, as someone else mentioned, if there ie evidence of the CFR on the dash, that can be used to get the serial number. But otherwise, it was either the small plate behind the passenger seat on the wheelwell, or the serial number on the data plate on the dash behind the chicken bar.
