From the sound of it, you have a spare actuator from a 123. Often, you can swap the little linkage ends, and use them in different areas/cars. Then again, if you can get a brand new diaphragm for 5 bucks, it would give you peace of mind that the part would last a few years longer when compared to a used part. (that's how the theory goes anyway)
