Pretty almost everything is from the 747, the sounds, the gauges, sad to see what happend to the beautiful 767 from P3D

1. This 767 cockpit has never been in P3D, it's built from scratch for MSFS2020.
2. The 767 gauges are not from the 747 because they don't exist on the 747.

As for the stock components, they are explained at the 763 page.

The last not the least, the "beautiful 767 from P3D" is $50 (fifty) more than the 767-III. Coincidence? I think not  ;)
