Tom, I have a '79 300SD, and I have the bolt.

I just went outside and read the tag on the side of my IP with a mirror and a flashlight. The tag is the Bosch governor designation, and it will tell you what year your pump is, and what governor you have.

There were two governor types in '79. The standard version, and the USA version. Perhaps the standard version is California???

My number was: RW 375/2200 MW 22 which is for USA 1978/1979. Green type rating plate.

You may have the Standard Version Which is up to 1980 and the number is: RW375/2200 MW 28-1.
