VW Badge location & body numbers, Challenge to determine beginning & end Options

[davep]

I require help with my research.
Typically, the VW badge was riveted to the right headlight bucket up to the end of 1974 and made its way to the right upper corner of the fuel tank bulkhead in 1975. Also, the body number was originally stamped into the rear trunk floor and made its was to a black riveted tag on the support below the right headlight bucket, as well as being found on the Karmann badge. At some point the body number base changed from xxy95zz to xxy90zz.

I require everyone to help with changeover VIN, and body number for each of the changes. Please add paint code and date code from the compliance decal as well.

i have worked out a bit more of the pattern.

fairly sure this is how it goes from examples of karmann ghias i could find relatively easily on BAT.

74 Karmann Ghia Cabriolets used 0 as the 5th numeral in the PKN number.



74 Karmann Ghia coupes used 1 as the 5th numeral.





KG production ceased at the end of june 1974.

1975 914s took over the KG PKN numbers using 0 and 1 as 5th numeral.
(except for those small number of exceptions that MCShack found - still unexplained - but maybe are errors?).

------

this car is currently for sale in australia.
pure luck coming across it - just hit the market.
1976 VW Scirocco. built dec75-jan76.
pkn # would say dec 18 1975.
just as the last 914s went out the door.

the PKN number is just legible in the images.
its 504-9590. the last two numbers are hard to read and not 100% but the 5th is clear as a 5.

looks like the scirocco did take over at least one of the earlier 914 numbers.
#5






in summary from 75 on.

914 = 0 and 1.
VW beetles use 2 (and potentially 3).
sciroccos use 5 (and potentially 4 and/or 6).
(EDIT INSERT. forgot i found a 79 scirocco a few weeks back with the 6 in as 5th number. safe to say that both the earlier 914 numbers of 5 and 6 went across to the sciroccos).

those three are the only vw models being made by karmann in model year 75/76.
no other cars being assembled/manufactured by karmann for other makes (eg BMW) use the PKN #. its a VW assigned number and is across all VW manufacturing sites and is not a unique Karmann convention.
