I wish I had the time and dimensions for you to make them up or just give you the info. I'm just far too busy......
The bushing has to be a press O.D. fit and a smooth 14/15 mm reamed hole (I forget the size) to pivot on. As well as the side to side dimension and overall length.
I use Delrin or UHMW for bushings, although they will never be as smooth as OEM greased needles. They are nearly indestructible though........
If you have a machinist friend, they can do the math and figure it out.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
