I started on these some time ago .....not having a shop sucks.
Finally got a chance to machine a few bits.
These shown are not completed, there will be threads tapped for adjuster bolt, and on the ends which will have a washer ok each side to complete the assembly..
They should be VERY light... just weighed them the way shown 93 grams for both... so likely around 105 or less, without the adjuster bolt.
Will have some ready soon..
