Congratulations, Gonzo! I'm glad your bike finally arrived.

For future reference, it helps if you hit the screwdriver with a hammer before you try to untighten the screws in the brake master cylinder. I think your best bet now is to carefully drill the heads off the stripped screws. Then you can remove the cap to the master cylinder. After the cap is removed, you should be able to loosen the screws with a pair of vise grips.

The other DF Bobber owners will probably have a definitive answer for you shortly regarding the rubber O-ring.

We eagerly await your photos!
