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.

Thanks Clay, that does indeed prove the use of the tag early in week 18.

Jon, yes the digits can be very hard to see. They were not done with any great precision, and are never as clear as the VIN in the front fender. Almost any accident in that corner will wrinkle the metal, then a bit of bondo and it is well hidden. Thankfully yours still exists.

I just need Dan to confirm, one way or the other, the presence of the tag in his front trunk. We may also need to find a few cars in week 15 and 17.

Lets not forget, we still have to start to nail down the change from base 9500 to base 9000 in the period of week 36 and week 37. These are the closest I have:
4752903042 3559575
4752901848 3749146

It has been only 13 years, but it is time to resurrect this thread so that new people can add new information. Two things that we are looking for: 1) VIN & Karmann # on the tag in the front trunk when it first appeared, or the last use of the rear trunk stamping. The Karmann # is also on the paint tag. 2) VIN & Karmann # on the tag in the front trunk when it changed from the base 9500 to base 9000. Paint tag and compliance decal photos also very useful. Do you have a CoA or window sticker? I need them also.

I logged on to find Dave with a similar question to ask and ran across this thread while searching the 1975 model year chassis numbers for cars made in Sept/Oct of 1974.

Years ago I started a small database on these cars and never got back to it until now.

Here is another to add on the base change from 9500 to 9000 chassis numbers.

VIN Number: 4752901849
Engine Number: EV Conversion
Chassis Number: 3749284
Build Date: 09/74
Paint Code/Color: L64K - Forest Green
