Sky mini-dish info

Unable to resist anything that 'might come in useful one day' I rescued a Sky mini-dish from a skip recently. The plastic LNB mount has long gone but I can easily design and print something new for the job. Could anyone supply the angle between the arm and the vertical face of the LNB to assist me please? I can see by walking up my road and looking at existing installations where it points, but rather than make something adjustable I'd like to make it fixed and spot-on from the get-go.
What gain does it have on 10Ghz is another question, compared to the slightly smaller (and long obsolete) BSB mini-dish? I'd guess its to do with obvious differences in capture area (they are both offset dishes) but will it make much difference?
Sky measures 43x58 cms vs BSB 35x42.

The BSB is built to a far superior standard and easier to manage in the field with fewer sharp edges.
Thanks
Gareth

Thanks, I printed one of those for trials pre-contest weekend but never got round to it. I was wanting to replicate for a 'normal' 40mm LNB too so based on your design I ended up with a 'up/down and angle' adjustable solution.
