I propose my solution for the support of my SR6.
you need :
- 4 screws M5, washers and butterfly bolt.
- Tempest max chair holder.
- On Amazon, https://www.amazon.fr/gp/product/B075B5QDJ4/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1
For mounting, looking at the pictures, it’s not wizarding.
If there is another suggestion, go there.
