Quantity: 2pc
Material: 6061 or 7075 Aluminum (6061 will be cheaper, but if you have surplus 7075 stock, either will work)
Finish: Raw
Tolerances: +/- 0.005"/0.13mm
Edit - I understand the tolerancing might be tight for some aspects of the design. The center bore and the 107.95 Radius that the 12 holes are on, are the two critical dimensions (as well as their concentricity). Otherwise, we can probably be a bit more open.
