I am confused with the distributor JFUR6 0231 116 51on my 230SL engine number 012501. Since the SL Group technical manual lists the correct rotor part number for both the -046 and the -051 distributors as 1234 332 088. How can this be, since the cam protrusion that the rotor fit to varies between these two. The -046 has a full length dia. of .560 inch from the cam, while the -051 is also .560 at the cam for a length of 1/8 inch and above that, for the length of the keyway the dia. is .510, or .050 smaller then the rotor bore.
Thanks for any help offered.
