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.

Jeff, you are correct, but I did not expect that it might extend so early into 1974. We may need to get a lot of responses to nail this down. I guess my problem is that I rarely see late '74 cars, and few from 1975 or 1976.

The split between 9500 and 9000 base is in either week 36 or week 37.
The last 9500 body is near 4752903042 and the first 9000 body is near 4752901848; that is quite an overlap.

It will be interesting to see if any '74' bodies were used in 1975 or '75' bodies in 1974. The latter looks highly unlikely now.
