USE R1 Aero Bar - Specs?

I’ve emailed USE twice (3 weeks ago and a follow up again last week) and haven’t gotten a response. For anyone who has the R1 installed, what are the following specs?

  1. Spacing between bolts. I really like 3T comfort cradles and will need the reach adjustability they have.
  2. What is the minimum stack height from the center of the clamp center to the bottom of the cradles with the extensions mounted over the bar? If you have an estimate for the under-mount stack height, that would be a bonus
