ive just required a 198B and S/Arm the frame is bent the S/Arm seems straight tho i did a test by holding the boss off the bush housing up to a straight edge no gaps. i plan on having the frame sorted and blasted and back to it's former glory in white. my question is on some off the later S/Arms did they not bother putting grease nipples on the bushes? just this 1 is blank there are no holes and it's not been filled as it;s bare metal.

There were no grease nipples on my 198B swing arm when new.

that explains it then.i was confused as my 199B has the grease nipples. i gess i could put some in before i have it sand blasted and painted. cheers
