Before you do anything, take the booster out and drain whatever fluid you have inside. Make sure the inside is clean and dry before you install a new mater cylinder. Brake fluid eats your booster and you will need a replacement if not done.

I have a few Opel master cylinders in stock, some used and some rebuilt. But I believe you should consider the Geo conversion since you will have better functionality and easier to get components. As an example, you can get a Geo master cylinder on Ebay for less than $30.00 all day long. You can also use a Honda master cylinder if you are considering installing rear disk brakes in the future. Make sure the master cylinders are from non-abs cars, makes the installation simpler.
