Decode dash number

[78-911SC]

Was stripping my car for the media blaster and came across
the number 1001688 stamped into the sheet metal just below the ashtray opening. These numbers where also on sheet metal under the dash just to the left of the steering wheel written in chalk. Anyone know what these numbers mean? They don't match the numbers on the post or in the trunk.

[911K]

That's the internal factory production number.

[B61]

i was trying to solve the same mystery for my 78 911sc targa

I found in this forum somewhere:

Yes, this is the commonly called the production #.
• The '1' is for 911.
• The '0' is for coupe ( '1' would be for a Targa and '2' would be for a Karmann coupe which was not used in '73).
• The '3' is for 1973.
• The # 5XXX is the sequential # of the body shell.

For me this worked since I have found number 1183812 on my dash
