If you're still searching out this one, here's something to ponder on. In the last 48 hours, I have seen TWO curved windshield Super Beetles, both with round, turn-knob glovebox locks. They were both '73 models....Interesting, I've not seen this before and am not sure if the doors are different as far as the hole where the latch mounts. But, if you snag one of these doors (and assuming they mount on the same hinges-I would not imagine them to be different), if your lock dies again, you can install the much cheaper and easier to procure knob.
