thread ended with summation by @davep - resident expert historian.



purpose of this thread is to condense the data found and edit out all the meanderings and discussion in original thread which is a bit much to punch through.

this will present the data found in a summarised form to assist anyone if they are interested or require this info for restoration purposes, or if just curious.

many thanks to @JeffBowlsby for his collection of option codes for 914s which goes someway to trying to sort this out - if its sorted out? ---> essential data.
and for asking the right questions along the way. (IMG:style_emoticons/default/beerchug.gif)

1975-76 CARS

no data was turned up for SIGLA screens in 1975-76.
only kinonglass windscreens.

the revision to the notation on the kinonglass screens is the inclusion of the audi symbol (4 rings) into the car manufacturer logo.
this may not occur at the start of the MY production but further into the model year (as is the case for other revisions in other model years, it does not necessarily co-incide with commencement of model year).
there appears to be slight differences in the D-code line at the bottom of the windscreen information line in terms of layout. one is centred, one is justified to edges.

additionally
the side glass tinted option changes in its notation from F to 1F.
the audi symbol (4 rings) is included with the VW logo.

example 1.
1975 porsche 914 1.8 "tinted" glass option. (screen and side glass).







example 2
1975 porsche 914 2.0 "tinted" windscreen glass option. (t screen and side glass)






note this car has a mixture of glass with logos.
windscreen is VW-audi logo.
side glass is VW logo.
vin number is 02519 which is earlier than example 1.
note: side glass manufacturer is different from windscreen manufacturer.
indicates that changeover in glass to a full set with VW-audi logos may not coincide with start of 75 MY or occur at same time with different manufacturers/suppliers.


example 3
1975 porsche 914 2.0 with "tinted" windscreen only option.






example 4
1976 porsche 914 2.0 "tinted" windscreen.



example 5
1976 porsche 914 2.0 clear windscreen.
