i think i need a couple of grease nipples for the swing arm pivot bolt for my 1978 3-1/12 sport do you know the dia and pitch of the thread of the grease nipple, so i can source grease nipples locally.
I replaced the left hand one with an angled one from NLM as I could not get the grease gun on, because of the LH exhaust pipe.which probably meant nor could the previous owner. I grease the things very often to try and avoid early wear. Not sure of thread though so no help there.
