Proper size of the black front brake mounting bolt (SM)?

[Salamander]

Does anyone happen to know the proper size and length of the top black mounting bolt for the front brake/reservoir/mirror assembly on the SM? Mine rattled out-- my fault. It's indicated by the top arrow in Figure 46 (page 52 in the manual).

A clone of the lower bolt doesn't seem to sit well against the reservoir bracket.

As with OE you will need to install a small spacer between the bracket and clamp. A small washer will suffice.
