Looking at the pictures in the original post, it seems like the "center disc" section of of the collars at Positions 2,3,4,5 are excessive diameter. The disc diameter is easily more than double that of the bolt head in Pos 3 & 4.
Why is that?
Is it just to make the collars all the same shape to ease manufacturing?
Is it to replace a washer so that a shorter bolt can be used? (I find this strange since a steel washer is probably much stiffer than a bronze disc)
The central disc portion at 1 & 6 seem to be a little larger than the washer. Not so bad, but I still see room for trimming the disc.
Any enlightenment is appreciated.
Does anyone know if the bolt going through the DogBone Mount needs to be replaced and what the part number is?
Thanks
