I wonder if maybe this is just a case of cheapness on VW's part? If you dig in a bit, you'll see that the screws they used bear the part number of the screws for early (and all Notchback -- now there's a mystery) 3-bolt door hinges. Maybe they had gazillions of them sitting around, or maybe they simply didn't have anything else that would fit. Who knows.

In any case, early T3 owners rejoice, you can steal a screw from a 4-bolt T3 drum when you strip a screw getting your doors off!
