This is the shop manual that Bitter dealers used. It is actually the Opel Monza/Senator manual.

This means that for example the body repair section exclusively refers to the respective Opels and is quite useless for the Bitter owner, but the mechanical sections of the manual do apply to the Bitter as they do for the Monza/Senator.

There might be the other odd piece of information that applies to the Opels only, but the manual is an extremely valuable resource to keep your Bitter in shape.

Distributor cap, Bosch. At this time we only have a cap in updated design in stock. It works without a problem in the Bitter, but the black dust-cap (Item 10) cannot be used with it. We still hope to find a batch of old style caps one of these days. So if you decide to use this new style cap, please keep your dust cap in a safe place, you might very well be able to use it again when we find the matching distributor caps.
