OK, so I don't know whether the wheel cylinders on my Beetle are '63, 65, or later. I do note that the wrench size on the front is very small (I don't have the proper box wrench for it) and the ones in back take a 7mm box wrench (and are larger).
I was wanting to buy a set of "speed bleeders" but find that they come in
6mm and 7mm sizes. Thanks,
